Okay , Once Download and install the latest version of the Windows App SDK from the official Microsoft page:

https://learn.microsoft.com/en-us/windows/apps/...

Corrupted Visual Studio cache can lead to issues like this. Try clearing the cache:

1: Close Visual Studio and navigate to the following folder:

%userprofile%\AppData\Local\Microsoft\VisualStudio{version}

2: Delete all files in the folder related to cache and temporary files.

3: Restart your PC and reopen Visual Studio.

Ensure all required dependencies are installed, especially if you are developing a UWP or WinUI app. Run the following in an elevated PowerShell prompt to ensure all required components are properly installed:

Get-WindowsCapability -Online | Where-Object { $_.Name -like 'Microsoft.WindowsAppRuntime*' } | Add-WindowsCapability -Online

    I tried the Run as Administrator earlier. There is no WindowsAppRuntime.msix file on my pc. But there are many like this:

    Microsoft.WindowsAppRuntime.1.7.msix

    Microsoft.WindowsAppRuntime.DDLM.1.7.msix

    Microsoft.WindowsAppRuntime.Main.1.7.msix

    Microsoft.WindowsAppRuntime.Singleton.1.7.msix

    I could (and may) try your method to force register it ... using the first on the list because it is closest to your instruction; but, one of the others may be better.

    Hello ,

    I’m here to help you in resolving your issue

    It looks like Windows App SDK isn't properly installed or registered, even though the installer claims success.

    1: Right-click WindowsAppRuntimeInstall-x64.exe(application installation file) > "Run as administrator"

    2: Restart and check if VS2022 works.

    If the runtime is installed but VS2022 doesn’t see it, force register it:

    1: Press Win +S > search for Powershell > Right click on it > click on Run as administrator > Run below commands

    Add-AppxPackage -Path "C:\Path\To\WindowsAppRuntime.msix"

    2: Replace "C:\Path\To\WindowsAppRuntime.msix" with the correct downloaded file path.

    After trying above steps, please reach out to me if you have any doubts or issues

    Help others by sharing your experience! Click “Yes” if this solution worked for you or “No” if it didn’t.
