Hi. I've been busting my butt with this one..
I had BitDefender Full Security 2009 installed, then, becuase I was stupid, I installed McAfee while BDnull was still installed. Took me a lot of time to straighten it up. I had to uninstall both programs. Now it's okay, but when I try to reinstall McAfee, it comes with the same message you guys got. And yes, I've tried the cmd thing, updated a new version of JavaScript and such, but nothing seems to work.
Running Vista Home Premium x64
Any help would be very much appreciated
happy
