For me, using Windows 7 Professional, 64-bit, Ver. 1494's "Clean and Fix My Computer" and "Registry Cleaner" fail to work. Same as above users; click on them and nothing happens. The screen just freezes. I have to click on the exit X several times to leave the program, and then go to Task Manager to end the process. \
Incidentally, I did as directed by Macecraft: I installed Version 1494 over the previous version.
