I was going to suggest doing a search on this topic, as it has certainly been answered before, but searching "vista 64" brings up essentially every windows thread.

Silverxxx is correct. XBMC will receive no additional help from a 64 bit computer OS, or, at least, none worth mentioning.

I'm fairly harsh with people on other forums on the whole searching rigamorale so I always look first. Problem is a search is only as good as the term used and when you're talking O/S' they are too generic to take.

Looks like I'll stick with 64 on the main PC and 32 on the HTPC.

Cheers
