7. ClickApply > OK .

Sometimes, third-party apps can hinder Windows functionality and affect its ability to install new software. Now, if there are too many apps for you to remember which one is allowed to change your system settings, you shouldperform a clean boot on Windows 11 .

This way, your system boots up with a minimal number of drivers and startup apps, so you can figure out if a background app is causing you issues. If everything works as usual, check the list of installed apps and remove the ones that may be causing conflict.

6. Re-Download the App and Install It

Windows might display the “make sure your temp folder is valid” error if the installer contains malware. In this case, re-download the app from the developer’s official website and stay away from pirated software, as it may contain hidden malware.

If you think your PC is infected, be sure toperform an offline scan with Microsoft Defender to ensure nothing is lurking in your PC.

7. Reset Your Computer

If nothing worked until now, and you can’t install anything on your computer, you shouldreset your computer . Fortunately, Windows allows you to use theCloud download option, so you can keep your files while it removes all third-party apps on your computer.
