The error message you are encountering indicates that the Microsoft.WindowsAppRuntime.dll file is either incompatible with your version of Windows or it may be corrupted. Here are some steps you can take to troubleshoot this issue:

1. Check Compatibility: Ensure that the version of the Windows App Runtime you are trying to use is compatible with your version of Windows. Check the system requirements for the specific version of the Windows App Runtime.
2. Reinstall the App Runtime: Sometimes, reinstalling the Windows App Runtime can resolve issues related to corrupted files. You can uninstall the current version and download the latest version from the Microsoft Store or the official Microsoft website.
3. Run System File Checker: Use the System File Checker tool to repair missing or corrupted system files. You can do this by running the command sfc /scannow in an elevated Command Prompt.
4. Check for Windows Updates: Ensure that your Windows operating system is up to date, as updates may include fixes for compatibility issues.
5. Event Viewer: Check the Event Viewer for any additional error messages that may provide more context about the issue. Look under Windows Logs > Application for any errors related to PhoneExperienceHost.exe or Microsoft.WindowsAppRuntime.dll.

If the problem persists after trying these steps, you may want to seek further assistance from Microsoft support or relevant forums.

Hi David,

It seems like the package for the Windows App Runtime is corrupt. Please download it from the link below:

You may have to confirm the download since the link is HTTP.

Once it is downloaded, open it and follow the on screen prompts.

I’m eager to hear back and work together to find a solution.
