Dude, chill out for a sec all your gonna do is piss people off by continually posting like that.
First off, make sure you running it as admin, also try running in compatibility for XP
Second, are you sure all your software is up to date? i.e. graphics drives, .net framework .etc
If that doesn't work, check it's not being stopped by antivirus or firewall? I would recommend disabling your AV and then try out CA.
