1. Restart Your Computer

Restarting your PC is the simplest solution to many Windows issues, including this one. It refreshes the system and resets the Microsoft Store service. So, if you are experiencing the “This app will not work on your device” error, restart your computer first and see if it works.

To restart your device, open the Start menu. Then select the Power icon and click Restart. You can also use the keyboard shortcut Ctrl + Alt + Del to open the same window. After restarting, try installing the app again and see if it works.

2. Clear the Microsoft Store Cache

If restarting your device does not help, the next step is to clear the Microsoft Store cache. This process removes any temporary files that might cause this issue. Clearing the cache removes unnecessary files and speeds up the browsing experience. Here’s how to clear the Microsoft Store cache.

A command prompt appears on the screen confirming that the Windows Store cache is cleared. Once you’ve completed these steps, check if it solves the error.

1. Open the Control Panel and view it in Category mode.
2. Go to Programs > Programs and Features > Turn Windows features on or off.
3. In the Windows Features dialog, scroll down to Hyper-V and check the box next to it.
   
4. Similarly, search for Virtual Machine Platform and Windows Hypervisor Platform and enable them as well.

5. Once done, click OK > Apply to save the changes.

Finally, restart your computer and check if the problem is resolved.

8. Perform Several Generic Windows Fixes

If none of the above solutions managed to fix the error, you can try performing several generic fixes. This includes running the System File Checker to scan for missing or corrupted files and the Deployment Image Servicing and Management tool to repair any corrupt system image.

You can also reset the Microsoft Store app to its default settings. This will reset the Store to its original configuration and potentially fix the error you’re experiencing.

If there are still problems, you can try performing a clean boot . It will launch the device with a minimal set of drivers and programs, allowing you to identify any 3rd-party applications that may be causing the error. Once done, restart your computer normally and check if the error has been fixed.
