Errr... if you're trying to run an EPG with Vista 64 bit then going by the posts by others recently I think you'll need to go back to 32 bit if you want an EPG to run flawlessly without other associated problems. It's taken the greater part of 2007 just to get the EPG to run properly under 32 bit!

This procedure will have you up and running under 32 bit in no time:
