2] Disable security software temporarily
The Installation assistant may not open due to third-party antivirus software; therefore, we recommend disabling all the antivirus software and then trying to open this utility. If there is no issue opening the Installation assistant is open, antivirus software was the one causing the problem. So, go ahead and disable Windows Defender and third-party antivirus if you have one, and then run the assistant; hopefully, it will do the trick.
3] Run System File Checker
Since Windows Installation assistant is a Windows tool, System File Checker can scan the protected system files, and if any corruption is detected, it will replace the file with cached ones.
Click Win + S to open the search box, type cmd, and run it with administrator rights. Now, to run System File Checker, type the following command and then hit the Enter button.
sfc/scannow
This will take some time, and once the whole process is completed, check whether the Installation assistant is back to its previous state.
4] Update the Graphics Driver as well as the OS
Outdated or corrupted graphics drivers can also be responsible for why you can’t open Installation Assistant on Windows 11. Hence, we recommend updating your device’s Graphics drivers as well as the current Operating system and then checking if the issue gets fixed.
5] Install Windows 11 using Media Creation Tool

Media Creation Tool will allow you to download the ISO file of Windows 11 that you can either run from the folder or mount it using an external drive. Either way, you will be able to install Windows 11 pretty easily.
