At this registry location, as shown in the above image, right-click over AppCompatFlags key and select Export. Save this key as registration file at a convenient location on your system for backup purpose. Now right-click the same key, i.e. AppCompatFlags and select Delete.
You can now close the Registry Editor and reboot the machine. After restarting the system, you should install Microsoft Office, in Clean Boot State. Let us know if you were able to resolve your issue following this procedure. Related read: Microsoft Office Professional Plus encountered an error during setup.
