some programs need to be run as administrator with windows 7 64 bit OS. To do that you right click on the icon, and select Run as Administrator (with the kite shield right next to it). You would think that this would be automatic if you are running windows without users, or on one account, but it doesn't, and however, some programs may not work properly running under Administrator anyway, but as you've noticed, some won't work very well without it. I have the same problem with XSplit, Ventrilo, and ISBoxer to name a few, but doing this fixes the issues.
