runs fine for me from inside the .zip on vista 32bit as well, for clydes issue could it be something to do with SP1 for vista? I have it installed but not everyone has it yet.
The only downside I have found so far with demos on vista on this PC setup is anything below 640*480 = fail if it goes fullscreen but that is ofc more drivers to blame (yet most works on my xp comp lol)
I have almost always had trouble with the little 4k and smaller demos tho, 90% never seem to bloody work for me anyway
