Adds relevant registry entries that allows any WebView2 enabled app to discover the runtime installed by Scoop.

Changes

  • Removed WEBVIEW2_BROWSER_EXECUTABLE_FOLDER since applications generally do not honor this.
    • An application must tell the WebView2 Loader to resolve the runtime from the variable.
  • The manifest now registers itself as only sole runtime for the current user & machine.
    • This unfortunately overrides any existing install from the system but allows applications to resolve and use the Scoop installed one.

Walkthrough

The manifest updates its notes to describe how the WebView2 Runtime overrides a natively installed Runtime for the current user or, for a global installation, the current machine. The installer and uninstaller add and remove Edge Update registry values. They use HKCU for per-user installations and select an HKLM path based on operating system architecture for global installations. The manifest no longer sets WEBVIEW2_BROWSER_EXECUTABLE_FOLDER.

Explanation

The title names the main change: it lets applications discover the WebView2 runtime that Scoop installs. It follows the conventional &lt;manifest-name&gt;: &lt;summary&gt; format, and the changeset touches only bucket/webview2.json. The title is accurate and specific.

Full details: Description check

Explanation

The description states the purpose of the change: registry entries let WebView2-enabled apps find the Scoop-installed runtime. It lists the removal of WEBVIEW2_BROWSER_EXECUTABLE_FOLDER and the override of system-wide installs, and it links references and related issue #17938. The template's conventional-title and contributing-guide checkboxes are ticked. The description omits the 'Closes/Relates to' line with a fully formed link, but it does include 'Relates to #17938', so the required information is present. The author also left the HTML comment block in place, which is harmless. Overall the description is mostly complete.

Do not overwrite another WebView2 installation.

If a native per-user runtime already owns these Edge Update values, the installer replaces its version and path. The new uninstaller then deletes those values rather than restoring them. A user who removes the Scoop package can therefore lose the native runtime’s registration. Preserve existing values and restore them only when Scoop still owns the values being removed. Microsoft identifies this pv location as the per-user runtime detection key. (learn.microsoft.com)

Account for global installations.

If a user installs this manifest with scoop install --global, the script still writes only to the installing account’s HKCU. Other accounts cannot discover the globally installed package through this registration. Define and test the intended global-install behavior before relying on these keys for discovery. Scoop documents a separate global install directory, while Microsoft distinguishes per-user and per-machine runtime detection keys. (github.com)

## Runtime or browser support during development or production

During development and testing, a WebView2 app can use either option as the backing web platform:

  * The WebView2 Runtime. The Runtime generally provides the same web platform capabilities and update release cadence as the Stable channel of the Microsoft Edge browser; see Microsoft Edge release schedule. You can adjust your workflow depending on your scenario. Sample code is available in the Samples repo.

###### Detect if a WebView2 Runtime is already installed

To verify that a WebView2 Runtime is installed, use one of the following approaches:

  * Approach 1: Inspect the `pv (REG_SZ)` regkey for the WebView2 Runtime at both of the following registry locations. The `HKEY_LOCAL_MACHINE` regkey is used for per-machine install. The `HKEY_CURRENT_USER` regkey is used for per-user install.

For WebView2 applications, at least one of these regkeys must be present and defined with a version greater than 0.0.0.0. If neither regkey exists, or if only one of these regkeys exists but its value is `null`, an empty string, or 0.0.0.0, this means that the WebView2 Runtime isn&#39;t installed on the client. Inspect these regkeys to detect whether the WebView2 Runtime is installed, and to get the version of the WebView2 Runtime. Find `pv (REG_SZ)` at the following two locations.

The two registry locations to inspect on 64-bit Windows:

Copy
    
    `HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}
    
    HKEY_CURRENT_USER\Software\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}
    `

The two registry locations to inspect on 32-bit Windows:

Copy
    
    `HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}
    
    HKEY_CURRENT_USER\Software\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}
    `

  * Approach 2: Run GetAvailableCoreWebView2BrowserVersionString and evaluate whether the `versionInfo` is `nullptr`. `nullptr` indicates that the WebView2 Runtime isn&#39;t installed. This API returns version information for the WebView2 Runtime or for any installed preview channels of Microsoft Edge (Beta, Dev, or Canary).

String fixedPath = Path.Combine(localFolder.Path, &quot;FixedRuntime\\(version number)&quot;);
## The Fixed Version runtime distribution mode

For constrained environments that have strict compatibility requirements, consider using the Fixed Version distribution mode. (The Fixed Version distribution mode was previously called bring-your-own.) For introductory information, see The Fixed Version runtime distribution mode in Evergreen vs. fixed version of the WebView2 Runtime.

In the Fixed Version distribution mode, you control the timing of updates to the WebView2 Runtime for your app. You download a specific version of the WebView2 Runtime and then package it with your WebView2 app. The WebView2 Runtime on the client isn&#39;t automatically updated. Instead, you periodically update the WebView2 Runtime that&#39;s packaged and distributed together with your updated app. The Fixed Version approach doesn&#39;t use a registry key for the WebView2 Runtime.

The Fixed Version binaries are over 250 MB and will make your app package larger by that amount.

To use the Fixed Version distribution mode:

  1. Download the Fixed Version of the WebView2 Runtime from Download the WebView2 Runtime, as a package.

The most-patched version of the latest and second-latest major releases are available for download at this site. Keep an archived copy of any versions you need.

  2. Decompress the WebView2 Runtime package using the command-line command `expand {path to the package} -F:* {path to the destination folder}` or by using a decompression tool such as WinRAR. Avoid decompressing through File Explorer, because that approach might not generate the correct folder structure.

  3. Include all of the decompressed Fixed Version binaries in your app package, to be deployed on the target machine during your app&#39;s installation.

  4. Indicate the path to the Fixed Version binaries when creating the WebView2 environment.

     * For Win32 C/C++, you can create the environment using the CreateCoreWebView2EnvironmentWithOptions function. Use the `browserExecutableFolder` parameter to indicate the path to the folder that contains the WebView2 runtime (`msedgewebview2.exe`).

     * For .NET, you must specify the environment before the WebView2 `Source` property takes effect. For .NET, you can use either of the following approaches to specify the environment:

       * Set the `CreationProperties` (WPF/WinForms) property on the `WebView2` element. Use the `BrowserExecutableFolder` member in the `CoreWebView2CreationProperties` (WPF/WinForms) class to indicate the path to the Fixed Version binaries.

       * Alternatively, use `EnsureCoreWebView2Async` (WPF/WinForms) to specify the environment. Use the `browserExecutableFolder` parameter in CoreWebView2Environment.CreateAsync to indicate the path to the Fixed Version binaries.

     * For WinUI, make sure the app has access to the folder by specifying the installed location and setting the environment variable for runtime path. One way to do this is by adding the following C# code to your app:

C#

Copy

#### CompareBrowserVersions

&gt; public STDAPI CompareBrowserVersions(PCWSTR version1, PCWSTR version2, int * result)

This method is for anyone want to compare version correctly to determine which version is newer, older or same.

Use it to determine whether to use webview2 or certain feature based upon version. Sets the value of result to `-1`, `0` or `1` if `version1` is less than, equal or greater than `version2` respectively. Returns `E_INVALIDARG` if it fails to parse any of the version strings or any input parameter is `null`. Directly use the `versionInfo` obtained from `GetAvailableCoreWebView2BrowserVersionString` with input, channel information is ignored.

#### CreateCoreWebView2Environment

&gt; public STDAPI CreateCoreWebView2Environment(ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler * environmentCreatedHandler)

Creates an evergreen WebView2 Environment using the installed WebView2 Runtime version.

This is equivalent to running `CreateCoreWebView2EnvironmentWithOptions` with `nullptr` for `browserExecutableFolder`, `userDataFolder`, `additionalBrowserArguments`. In this scenario, the API tries to find a compatible version of the WebView2 Runtime that is installed on the user machine (first at the machine level, and then per user) using the selected channel preference. The path of fixed version of the WebView2 Runtime should not contain `\Edge\Application\`. When such a path is used, the API fails with `HRESULT_FROM_WIN32(ERROR_NOT_SUPPORTED)`.

By default, the channel search order is `COREWEBVIEW2_CHANNEL_SEARCH_KIND_MOST_STABLE`, which means that environment creation searches for an installation in the following order: the WebView2 Runtime, Beta, Dev, and Canary. The channel search order is reversed when the `ChannelSearchKind` property on ICoreWebView2EnvironmentOptions is set to `COREWEBVIEW2_CHANNEL_SEARCH_KIND_LEAST_STABLE`, or when the corresponding environment variable or registry override is set to `1`. See below for descriptions of overrides. If `ReleaseChannels` on ICoreWebView2EnvironmentOptions is provided, environment creation will only consider channels in this set, following the `ChannelSearchKind` order.
If not set, then this forwarding will not occur and creation will fail if there is already a different WebView2 Runtime running for the specified user data folder.

The `runtimeType` parameter is used to indicate if the WebView2 Runtime is fixed version with value `1`, evergreen with value `0`, or unknown with value `-1`.

See the `CreateCoreWebView2EnvironmentWithOptions` documentation for information on the `userDataFolder`, `environmentOptions`, and `webViewEnvironmentCreatedHandler` parameters which match the parameters from `CreateCoreWebView2EnvironmentWithOptions`.

This is unlike `CreateCoreWebView2EnvironmentWithOptions` which handles many other cases including: falling back to other non-stable WebView2 Runtime channels when the stable WebView2 Runtime is not available, handling developer environment variables to change the runtime, handling policy registry keys to change the runtime, and others. You should use `CreateCoreWebView2EnvironmentWithOptions` rather than this method.

If `checkRunningInstance` is set then `CreateWebViewEnvironmentWithOptionsInternal` will forward the creation call to a different WebView2 Runtime if there is already a different WebView2 Runtime running for the specified user data folder. This matches `CreateCoreWebView2EnvironmentWithOptions` behavior. If not set, then this forwarding will not occur and creation will fail if there is already a different WebView2 Runtime running for the specified user data folder.

The `runtimeType` parameter is used to indicate if the WebView2 Runtime is fixed version with value `1`, evergreen with value `0`, or unknown with value `-1`.

Get the browser version info including channel name if it is not the WebView2 Runtime.

Channel names are Beta, Dev, and Canary. If an override exists for the `browserExecutableFolder` or the channel preference, the override is used. If an override is not specified, then the parameter value passed to `GetAvailableCoreWebView2BrowserVersionString` is used. Returns `HRESULT_FROM_WIN32(ERROR_FILE_NOT_FOUND)` if it fails to find an installed WebView2 runtime or non-stable Microsoft Edge installation.

The caller must free the returned string with `CoTaskMemFree`. See API Conventions.</excerpt>

Do not register the Fixed Version runtime as Evergreen.

Microsoft documents that Fixed Version deployment does not use a WebView2 runtime registry key. An application can therefore read the registered pv value, skip its Evergreen installation, and still fail unless it passes the Fixed Version folder to WebView2. Keep WEBVIEW2_BROWSER_EXECUTABLE_FOLDER for applications that honor the override, but remove the pv and EBWebView registry scripts.

Remove the installer and uninstaller registry scripts in the WebView2 manifest,
including the writes and deletes for the `pv` and `EBWebView` values. Keep
`WEBVIEW2_BROWSER_EXECUTABLE_FOLDER` so applications that honor the override can
locate the Fixed Version runtime.

@Aetopia The note makes the intentional per-user override clear. I withdraw the objection to overwriting those values as an unintended change.

The uninstall concern remains separate: the script deletes pv and EBWebView without restoring the previous values or checking ownership. The note documents the override, but it does not address that cleanup risk.

Scope the registry note to non-global installs.

When $global is true, the scripts skip the HKCU registry operations. Line [10] currently presents the HKCU override as unconditional. State that this override applies only to regular installs. Document separately that global installs use the system environment variable.

The official Scoop manifest guide documents the different env_set scopes and supports notes arrays. (raw.githubusercontent.com)

Replace break with return in the global-install guards.

break is a loop control statement in PowerShell. It does not return from the hook script block. Inside a hook, break can end the hook early. It can also exit an enclosing loop in the calling Scoop code. For a global install, this can stop the process before later steps run, such as linking current, setting the environment variable, and saving install metadata. For a global uninstall, this can skip the remaining cleanup.

return ends only the hook. The registry steps after the guard are skipped, and Scoop continues.

Proposed fix and validation
-            "if ($global) { break }",
+            "if ($global) { return }",

Apply the same change to the matching $global guard in the uninstaller script.

<title>Distribute your app and the WebView2 Runtime - Microsoft Edge Developer documentation | Microsoft Learn</title>

<excerpt>citeturn1view1 [wordlim: 200] Crawled: last week; Content type: text/html; Source: open({&quot;ref_id&quot;:&quot;turn0search5&quot;,&quot;lineno&quot;:null}); Redirected to URL: https://learn.microsoft.com/en-us/microsoft-edge/webview2/concepts/distribution?form=MA13LM; Total lines: 379
L66: Requiring the production version of a WebView2 app to use the WebView2 Runtime rather than the browser allows the WebView2 app to stay evergreen even if browser updates are prevented by the clients&#39; admin.
L67:   * As opposed to the browser, the WebView2 Runtime is developed and tested for app scenarios, and in some cases the WebView2 Runtime might include bug fixes that aren&#39;t yet available in the browser.
L68: The Evergreen WebView2 Runtime will be included as part of the Windows 11 operating system. Various WebView2 apps have installed the Evergreen Runtime on devices with an operating system prior to Windows 11. However, some devices might not have the Runtime pre-installed, so it&#39;s a good practice to check whether the Runtime is present on the client.
L69: Before your app creates a WebView2, the app should check whether the WebView2 Runtime is present (either by checking a registry key or by calling an API) and install the Runtime if it is missing. The app can do this check when installing or updating your app (recommended), or at app runtime. To check whether the Runtime is present, see 【10†Deploying the Evergreen WebView2 Runtime】, below.
L70: ## The Evergreen Runtime distribution mode
L71: 
L72: The Evergreen distribution mode ensures that your WebView2 app is taking advantage of the latest WebView2 features and security updates. For introductory information, see 【25†The Evergreen Runtime distribution mode】 in Evergreen vs. fixed version of the WebView2 Runtime.
L73: 
L74: The Evergreen distribution mode has the following characteristics:
L75:   * The WebView2 Runtime updates automatically without requiring any action from you. It receives the same Microsoft Edge updates that are described in 【26†Release notes for Microsoft Edge Stable Channel】 and 【27†Release notes for Microsoft Edge Security Updates】.
L76: 
L77:   * All WebView2 apps that use the Evergreen distribution mode use a shared copy of the Evergreen WebView2 Runtime, which saves disk space.
L78:   * On eligible systems, binaries for Microsoft Edge and the Evergreen WebView2 Runtime are hard-linked together when they are on the same version. This linking provides benefits for disk footprint, memory, and performance.
L79: When you use the Evergreen distribution mode of the WebView2 Runtime, your WebView2 app assumes that clients have the latest Runtime. Your app cannot require a particular version of the WebView2 Runtime for all apps on the client. By the time a new WebView2 SDK package is released, a compatible version of the WebView2 Runtime has already been distributed to clients. Therefore it&#39;s OK for your WebView2 app to use the APIs that are in the latest version of the WebView2 SDK.
L80: #### Windows 11 devices and Windows 10 devices (details)
L81: 
L82: For introductory information, see 【28†Windows 11 devices and Windows 10 devices】 in Evergreen vs. fixed version of the WebView2 Runtime.
L83: The vast majority of Windows 10 devices have the WebView2 Runtime installed already, as described in 【29†Delivering Microsoft Edge WebView2 Runtime to managed Windows 10 devices†blogs.windows.com】. A small number of Windows 10 devices don&#39;t have the WebView2 Runtime installed. We recommend that you handle this edge case, by using either of the following approaches:
L84: 
L85:   * Programmatically deploy the Evergreen Runtime with your app. See 【10†Deploying the Evergreen WebView2 Runtime】 below.
L86:   * Redirect your end users to the Microsoft site: 【30†Download Microsoft Edge WebView2†developer.microsoft.com】, and have end users download the Evergreen WebView2 Runtime installer from the site and install the Runtime themselves.

#### CompareBrowserVersions

&gt; public STDAPI CompareBrowserVersions(PCWSTR version1, PCWSTR version2, int * result)

This method is for anyone want to compare version correctly to determine which version is newer, older or same.

Use it to determine whether to use webview2 or certain feature based upon version. Sets the value of result to `-1`, `0` or `1` if `version1` is less than, equal or greater than `version2` respectively. Returns `E_INVALIDARG` if it fails to parse any of the version strings or any input parameter is `null`. Directly use the `versionInfo` obtained from `GetAvailableCoreWebView2BrowserVersionString` with input, channel information is ignored.

#### CreateCoreWebView2Environment

&gt; public STDAPI CreateCoreWebView2Environment(ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler * environmentCreatedHandler)

Creates an evergreen WebView2 Environment using the installed WebView2 Runtime version.

This is equivalent to running `CreateCoreWebView2EnvironmentWithOptions` with `nullptr` for `browserExecutableFolder`, `userDataFolder`, `additionalBrowserArguments`. For more information, navigate to `CreateCoreWebView2EnvironmentWithOptions`.

#### CreateCoreWebView2EnvironmentWithOptions

&gt; public STDAPI CreateCoreWebView2EnvironmentWithOptions(PCWSTR browserExecutableFolder, PCWSTR userDataFolder, ICoreWebView2EnvironmentOptions * environmentOptions, ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler * environmentCreatedHandler)

DLL export to create a WebView2 environment with a custom version of WebView2 Runtime, user data folder, and with or without additional options.

When WebView2 experimental APIs are used, make sure to provide a valid `environmentOptions` so that WebView2 runtime knows which version of the SDK that the app is using. Otherwise, WebView2 runtime assumes that the version of the SDK being used is the latest version known to it, which might not be the version of the SDK being used. This wrong SDK version assumption could result in some experimental APIs not being available.

The WebView2 environment and all other WebView2 objects are single threaded and have dependencies on Windows components that require COM to be initialized for a single-threaded apartment. The app is expected to run `CoInitializeEx` before running `CreateCoreWebView2EnvironmentWithOptions`.

userDataFolder can be specified to change the default user data folder location for WebView2. The path can be an absolute file path or a relative file path that is interpreted as relative to the current process&#39;s executable. Otherwise, for UWP apps, the default user data folder will be the app data folder for the package; for non-UWP apps, the default user data folder `{Executable File Name}.WebView2` will be created in the same directory next to the app executable. WebView2 creation can fail if the executable is running in a directory that the process doesn&#39;t have permission to create a new folder in. The app is responsible to clean up its user data folder when it is done.

Use `browserExecutableFolder` to specify whether WebView2 controls use a fixed or installed version of the WebView2 Runtime that exists on a user machine. To use a fixed version of the WebView2 Runtime, pass the relative folder path that contains the fixed version of the WebView2 Runtime to `browserExecutableFolder`.

In this scenario, the API tries to find a compatible version of the WebView2 Runtime that is installed on the user machine (first at the machine level, and then per user) using the selected channel preference. The path of fixed version of the WebView2 Runtime should not contain `\Edge\Application\`. When such a path is used, the API fails with the following error.

Note

As a browser process may be shared among WebViews, WebView creation fails with `HRESULT_FROM_WIN32(ERROR_INVALID_STATE)` if the specified options does not match the options of the WebViews that are currently running in the shared browser process.

`environmentCreatedHandler` is the handler result to the async operation that contains the `WebView2Environment` that was created.

#### CreateCoreWebView2EnvironmentWithOptions

&gt; public STDAPI CreateCoreWebView2EnvironmentWithOptions(PCWSTR browserExecutableFolder, PCWSTR userDataFolder, ICoreWebView2EnvironmentOptions * environmentOptions, ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler * environmentCreatedHandler)

DLL export to create a WebView2 environment with a custom version of WebView2 Runtime, user data folder, and with or without additional options.

When WebView2 experimental APIs are used, make sure to provide a valid `environmentOptions` so that WebView2 runtime knows which version of the SDK that the app is using. Otherwise, WebView2 runtime assumes that the version of the SDK being used is the latest version known to it, which might not be the version of the SDK being used. This wrong SDK version assumption could result in some experimental APIs not being available.

The WebView2 environment and all other WebView2 objects are single threaded and have dependencies on Windows components that require COM to be initialized for a single-threaded apartment. The app is expected to run `CoInitializeEx` before running `CreateCoreWebView2EnvironmentWithOptions`.

Use `browserExecutableFolder` to specify whether WebView2 controls use a fixed or installed version of the WebView2 Runtime that exists on a user machine. To use a fixed version of the WebView2 Runtime, pass the folder path that contains the fixed version of the WebView2 Runtime to `browserExecutableFolder`. BrowserExecutableFolder supports both relative (to the application&#39;s executable) and absolute files paths. To create WebView2 controls that use the installed version of the WebView2 Runtime that exists on user machines, pass a `null` or empty string to `browserExecutableFolder`. `environmentCreatedHandler` is the handler result to the async operation that contains the `WebView2Environment` that was created.

Correct the per-user override note.

Microsoft documents that CreateCoreWebView2EnvironmentWithOptions with a null browserExecutableFolder searches for a compatible runtime at the machine level before the per-user level. A compatible machine runtime can therefore take precedence over this HKCU registration. Reword the note instead of claiming that a normal install overrides a machine runtime.

Suggested note update
-        "Overrides any natively installed Runtime for the current user.",
-        "If being globally installed then for the current machine."
+        "Registers the Scoop Runtime for the current user.",
+        "If being globally installed, registers it for the current machine. WebView2 searches for a compatible runtime at machine level before per-user level."

Review comment at @bucket/webview2.json at line 32:
Reword the note associated with the HKCU registration in the WebView2 manifest
so it describes registering the Scoop Runtime for the current user, not
overriding a natively installed Runtime. Clarify that global installation
registers it for the machine and that WebView2 searches for a compatible
machine-level runtime before a per-user runtime.

<excerpt>citeturn0search3 [wordlim: 200] Crawled: 2 weeks ago; The Runtime generally provides the same web platform capabilities and update release cadence as the Stable channel of the Microsoft Edge browser; see Microsoft Edge release schedule. ... If a WebView2 app required the presence of Microsoft Edge on the client, that would potentially have unintended side-effects on the WebView2 app. ... Before your app creates a WebView2, the app should check whether the WebView2 Runtime is present (either by checking a registry key or by calling an API) and install the Runtime if it is missing.
Many devices in enterprises and in education are disconnected from Windows Update or aren&#39;t managed by Microsoft directly. Such devices might not have Microsoft Edge installed. Requiring the production version of WebView2 apps to use the WebView2 Runtime rather than Microsoft Edge avoids making Microsoft Edge a prerequisite for running a WebView2 app.

  * Browsers and apps have different use cases. If a WebView2 app required the presence of Microsoft Edge on the client, that would potentially have unintended side-effects on the WebView2 app. For example, an IT Admin can prevent the browser from being updated from a specific version, to keep the browser compatible with an internal website. Requiring the production version of a WebView2 app to use the WebView2 Runtime rather than the browser allows the WebView2 app to stay evergreen even if browser updates are prevented by the clients&#39; admin.

  * As opposed to the browser, the WebView2 Runtime is developed and tested for app scenarios, and in some cases the WebView2 Runtime might include bug fixes that aren&#39;t yet available in the browser.

The Evergreen WebView2 Runtime will be included as part of the Windows 11 operating system. Various WebView2 apps have installed the Evergreen Runtime on devices with an operating system prior to Windows 11. However, some devices might not have the Runtime pre-installed, so it&#39;s a good practice to check whether the Runtime is present on the client.

Before your app creates a WebView2, the app should check whether the WebView2 Runtime is present (either by checking a registry key or by calling an API) and install the Runtime if it is missing. The app can do this check when installing or updating your app (recommended), or at app runtime. To check whether the Runtime is present, see Deploying the Evergreen WebView2 Runtime, below.

###### Detect if a WebView2 Runtime is already installed

To verify that a WebView2 Runtime is installed, use one of the following approaches:

  * Approach 1: Inspect the `pv (REG_SZ)` regkey for the WebView2 Runtime at both of the following registry locations. The `HKEY_LOCAL_MACHINE` regkey is used for per-machine install. The `HKEY_CURRENT_USER` regkey is used for per-user install.

For WebView2 applications, at least one of these regkeys must be present and defined with a version greater than 0.0.0.0. If neither regkey exists, or if only one of these regkeys exists but its value is `null`, an empty string, or 0.0.0.0, this means that the WebView2 Runtime isn&#39;t installed on the client. Inspect these regkeys to detect whether the WebView2 Runtime is installed, and to get the version of the WebView2 Runtime. Find `pv (REG_SZ)` at the following two locations.

The two registry locations to inspect on 64-bit Windows:

Copy
    
    `HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}
    
    HKEY_CURRENT_USER\Software\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}
    `

The two registry locations to inspect on 32-bit Windows:

Copy
    
    `HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}
    
    HKEY_CURRENT_USER\Software\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}
    `

  * Approach 2: Run GetAvailableCoreWebView2BrowserVersionString and evaluate whether the `versionInfo` is `nullptr`. `nullptr` indicates that the WebView2 Runtime isn&#39;t installed. This API returns version information for the WebView2 Runtime or for any installed preview channels of Microsoft Edge (Beta, Dev, or Canary).

Run this command from a non-admin PowerShell to install scoop with default configuration, scoop will be install to `C:\Users\&lt;YOUR USERNAME&gt;\scoop`. ... You can use proxies if you have network trouble in accessing GitHub.

# Scoop (un)installer

## Installation

### Prerequisites

PowerShell latest version or Windows PowerShell 5.1

  * The PowerShell Language Mode is required to be `FullLanguage` to run the installer and Scoop.

  * The PowerShell Execution Policy is required to be one of `RemoteSigned`, `Unrestricted` or `ByPass` to run the installer. For example, it can be set to `RemoteSigned` via:
    
    Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

### Typical Installation

Run this command from a non-admin PowerShell to install scoop with default configuration, scoop will be install to `C:\Users\&lt;YOUR USERNAME&gt;\scoop`.
    
    irm get.scoop.sh | iex

You can use proxies if you have network trouble in accessing GitHub.
    
    iex &quot;&amp; {$(irm get.scoop.sh -Proxy &#39;http://&lt;ip:port&gt;&#39;)} -Proxy &#39;http://&lt;ip:port&gt;&#39;&quot;
    
    # or
    $env:HTTP_PROXY=&#39;http://&lt;ip:port&gt;&#39;
    $env:HTTPS_PROXY=&#39;http://&lt;ip:port&gt;&#39;
    irm get.scoop.sh | iex

### Advanced Installation

If you want to have an advanced installation, you can download the installer and manually execute it with parameters.
    
    irm get.scoop.sh -outfile &#39;install.ps1&#39;

To see all configurable parameters of the installer.
    
    .\install.ps1 -?

For example, you could install scoop to a custom directory, configure scoop to install global programs to a custom directory, and bypass system proxy during installation. The custom directories should be absolute paths.
    
    .\install.ps1 -ScoopDir &#39;D:\Applications\Scoop&#39; -ScoopGlobalDir &#39;F:\GlobalScoopApps&#39; -NoProxy

Or you can use the legacy method to configure custom directory by setting Environment Variables.
    
    $env:SCOOP=&#39;D:\Applications\Scoop&#39;
    $env:SCOOP_GLOBAL=&#39;F:\GlobalScoopApps&#39;
    [Environment]::SetEnvironmentVariable(&#39;SCOOP_GLOBAL&#39;, $env:SCOOP_GLOBAL, &#39;Machine&#39;)
    irm get.scoop.sh | iex

#### For Admin

Installation under the administrator console has been disabled by default for security considerations. If you know what you are doing and want to install Scoop as administrator. Please download the installer and manually execute it with the `-RunAsAdmin` parameter in an elevated console. Here is the example:
    
    irm get.scoop.sh -outfile &#39;install.ps1&#39;
    .\install.ps1 -RunAsAdmin [-OtherParameters ...]

What if I don&#39;t care and just want a one-line command:
    
    iex &quot;&amp; {$(irm get.scoop.sh)} -RunAsAdmin&quot;

#### CI Pipeline

It&#39;s common to use Scoop in CI pipelines to install tools. Here is an example for GitHub Actions:
    
    - name: Install Scoop
      shell: pwsh
      run: irm get.scoop.sh | iex

If the CI environment does not have the `$env:CI` variable set, you might need to explicitly `exit $LASTEXITCODE` to propagate the installation result to the pipeline, or set `$env:CI` before the installation command.

### Silent Installation

You can redirect all outputs to Out-Null or a log file to silence the installer. And you can use `$LASTEXITCODE` to check the installation result, it will be `0` when the installation success.
    
    # Omit outputs
    .\install.ps1 [-Parameters ...] | Out-Null
    # Or collect logs
    .\install.ps1 [-Parameters ...] &gt; install.log
    # Get result
    $LASTEXITCODE

Select the 32-bit registry view for global installs.

$X86 describes the OS architecture, but the default reg.exe view depends on the PowerShell process that launches it. In a native 64-bit context, the current x64 and ARM64 branch writes plain HKLM\SOFTWARE to the 64-bit view. On x86, it adds WOW6432Node to a path that should remain plain HKLM\SOFTWARE. These locations do not match WebView2's machine-runtime lookup paths.

Use plain HKLM\SOFTWARE with /reg:32 for both global installation and uninstallation. This is correct on x86 and explicitly selects the 32-bit view on x64 and ARM64.

Update the global install and uninstall registry commands in the webview2
configuration to use plain HKLM\SOFTWARE and explicitly select the 32-bit
registry view with /reg:32. Remove the OS-architecture-based $X86 and $Key path
selection; apply the same view to both reg.exe add and reg.exe delete
operations.

Preserve existing WebView2 registration during uninstall.

If a native runtime already owns these values, installation replaces them. Uninstallation then deletes the values without restoring the native registration. The global branch makes this failure apply to the machine-wide registration as well as the per-user registration. WebView2 uses these registry locations for runtime detection. (learn.microsoft.com)

Store the previous pv and EBWebView values during installation. Restore them only when the current values still match Scoop's $version and $dir; otherwise leave the newer registration unchanged. This repeats the existing ownership concern.

I should maybe add a note on how one can restore their original installation.

@Aetopia A recovery note would help, especially because overriding the native runtime is intentional.

State that uninstalling Scoop’s runtime does not restore the previous registry values. Include a tested recovery procedure for both per-user and global installations.

The note would document recovery, but it would not address the full finding: the uninstaller also deletes these values if another installer has changed them since Scoop’s installation. An ownership check is still needed to preserve that newer registration.

@Aetopia Thanks. The note now documents how to restore the native runtime.

The ownership concern remains separate. In the supplied code, uninstall still deletes pv and EBWebView even if another installer has replaced those values since Scoop’s installation. The recovery note does not protect that newer registration.
