Hi everyone

So I have some trouble with installing catalyst control center on my pc. I just formatted it and I constantly get the same errors. The installation itself works without problems, after restart however I first get an error that says "windows sidebar has stopped working" followed by the error "load mmdrive application has stopped working" and this one is followed by "catalyst control center host application has stopped working". the last two errors keep coming back everytime I try to restart CCC. 

Yes I have installed .net framework 3.5 and tried the 4.0 for the last version. I also tried the drivers that are on the disk I got with the graphics card and have always uninstalled the previous installed version first. Formatting the pc again also doesn't seem to do the trick.

My pc is running on Vista ultimate 64bit. Untill a few months ago it all worked perfectly

I hope someone knows how I can solve this
