Answer 1

Type regedit in the search on the taskbar to launch Registry.

Go to:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients\

Right click on {F3017226-FE2A-4295-8BDF-00C3A9A7E4C5} and delete it.

Go to this link https://developer.microsoft.com/microsoft-edge/webview2?form=MA13LH

Download and install Webview2.

Answer 2

The error message indicates that the app’s embedded Microsoft Edge WebView2 runtime cannot read or write to its data directory under C:\ProgramData\temp\...WebView2\EBWebView. This is typically caused by antivirus/security software or permissions on that folder.

To resolve it, try these steps in order:

1. Temporarily disable or adjust antivirus/security software and try launching the app again. If it works, add an exception for the app and its WebView2 data folder so the antivirus does not block or lock it. A similar issue with attachments failing to download was resolved after an antivirus update and configuration change.
2. Ensure the Windows user account has full read/write permissions to C:\ProgramData\temp and any subfolders created by the game/installer.
3. Install all pending Windows Updates and Microsoft Edge / WebView2 Runtime updates, then restart the PC and try again.
4. If the problem persists only for a specific user profile, create a new Windows user profile and test there. If it works in the new profile, the original profile’s WebView2 data or permissions may be corrupted and may need cleanup or recreation.

If none of these steps help, contact the game’s support and provide the full error text and path so they can confirm the correct WebView2 configuration and any required exclusions.
