I've used jv16 PowerTools X on my Windows 7 PC (Windows 7 Professional Service Pack 1 64 bit). I have admin rights on this PC.


I got at CFMC and Registy Compactor follow error message: Failed to modify "HKEY_LOCAL_MACHINE\System\Setup\"!

Every operation to modify the system registry goes through Windows: programs cannot directly edit the registry, they can only ask Windows to make the modifications they need. This error message means that PowerTools asked to modify the specific registry key but Windows said "no".


Unfortunately, there is very little we can do about this.
