Noticed that you are running Vista...there in lyes your compatibility problems with these programs.
If these programs don't want to work, then try running them in XP Compatibility mode.
Also, the only program that seems to work for overclocking your graphics card in Vista is RivaTuner...
I tested this out using Vista Ultimate SP1. OK...
Although I only have a few posts here, I've been overclocking my graphics cards and comp systems for years...
