Uninstall this app now because it isn’t compatible with Windows 11/10

Steps to remove blocking applications

The reason Windows Upgrade fails, is because of apps that are not compatible with the next version of Windows. Chances are that they would work, but they haven’t passed through the compatibility check. When you run Windows 10 Upgrade Advisor, the system checks for such apps and warns you. The same happens during every upgrade. While it usually should not block, but things don’t go straight all the time. Many a time it may so happen that the app is not installed on your PC, but it is likely that the compatibility checker is detecting a file associated with the app, rather than the app itself. You will need to delete the file it is detecting before you can install the upgrade. You can determine which file is triggering the block by examining a hidden log file. To do this, follow these steps:

PowerShell Script to fix remove blocking applications

If you find the above step difficult, you can download this PowerScript file from Microsoft, and run it when you face this blocking application error. A zip file with the name AppRPS.zip will download on your computer. Once you had unzipped the script file, run it with Administrator privilege. Once the blocking file is moved or deleted, try installing the Windows 10 upgrade again, or return to the Windows 10 Upgrade Assistant and select the Refresh button. Hope this helps!
