A friend of mine works for Microsoft. What he has had me do on many applications and drivers is to go to properties and then compatibility and put in Vista SP1. This has worked for all my Logitech drivers including Web Cam. Games Like DAOC I had to do this. It's not a guarantee but all my applications and seem to work fine.
