msmouse.inf is corrupted.


  1. Please replace corrupted C:\Windows\System32\DriverStore\FileRepository\msmouse.* folder with the good one. You should copy it from another Windows computer (physical or virtual) which does not experience the mouse-related issues (computer with the same Windows OS, same bit version).

  2. Run Parallels Tools installation.
