Then turn your system back on, run the problematic application setup again, and see if the problem is resolved. Now shut down your system and wait for 1 minute. Also, completely close all applications on your system and use the task manager and taskbar to make sure no background applications are running (the task manager should only run system processes).

Some users have also encountered a “File missing” error message when starting the system.
