Error opening file for writing: Bootor64.sys
Posted by CompuClever Support Team on 29 September 2015 04:30 PM

During uninstall or program update on Windows 10, some users may encounter an error message: 

"Error opening file for writing: C:\Program Files (x86)\CompuClever\PCTuneUpMaestro\Bootor.sys"

To resolve this issue, you need to stop a Windows service, used by the StartUp Management and installed by PCTuneUpMaestro.

Please follow the steps below:

  • Start Command Prompt as an Administrator. (View this article to learn how...)
  • In the command prompt window type this command (without the double-quotes): "sc stop CompuCleverBootor"
  • Press the Enter key

This should stop the CompuCleverBootor driver and you can uninstall or re-install PCTuneUpMaestro

Our development team is currently fixing this issue and we will report back once the status changes.
