  1. Open the Control Panel by searching for it in the Start menu. You can also use the Windows + R key combination, type “control.exe” in the “Run” window that appears, and then click OK.

  3. Open it and click on “Change User Account Management Settings.”
    You’ll notice that there are several different levels that you can select on the security slider.
  4. Try reducing that value by one if it’s on the highest slider, and see if that helped after you run the problematic program. Repeat the process if the error still persists.
  5. We recommend disabling user account management for a while, as it is likely that the program should run successfully, and then try to reactivate it.
