Error Sysprep Was Not Able to Validate Your Windows installation on Windows 10

We encountered an error message "'Sysprep Was Not Able to Validate Your Windows installation" when trying to sysprep a Windows 10 virtual machine.

[ Resolution]

Navigate to C:\Windows\System32\Sysprep\Panther and open setupact.txt



We found out the problem was a Twitter app was installed from Windows Store and prevented us from sysprep.

Therefore, we uninstall the app. We advise you to check the setupact.txt to identify which app that is causing the problem.


Lastly Run sysprep command with administrative rights.

Hope this help.
