The Steam and Fileplanet demo's will not work on my system.

Vista 64bit
Core2Quad Q9400 2.66ghz
4 gigs Ram
HD 5570 1 gig DDR3
23" LED/LCD 1080p monitor

I've tried all compatibility modes, but to no avail. I think the error message is the typical "The program has stopped working" , whenever I click on the desktop icon.

Does the full version (GOG version) of Psychonauts work on Win Vista/7? It is just really hard to tell sometimes. Thanks in advance.

Runs just fine on my Win7 64 bit system.

Likewise on my laptop. The GOG version probably isn't any more patched than the Steam version (which is what I have). It's possible that the demo is an earlier version that's less stable or something though.
