After 11 Phillips support phone calls...I finally spoke with someone that really understood the situation..... "Drivers intermittently working on 32-bit Vista systems and not at all on 64." According to him the software engineer crew from Belgium visits US corporate every so often, each time customer support staff get a chance to discuss customer issues, each time the engineer's hear many complaints about pronto owners not being able to use their remotes on their vista systems. Their answer so far, no intention of making drivers. Are you serious!?

My answer, no problem, have owned three pronto remotes, my next remote will be from another company that respects their customers....
