I downloaded the demo to make sure the game will run on my PC before I buy it, and (not so) surprisingly, it does not. After starting up the demo, I see a spash screen, then the usual windows "xxx.exe closed unexpectedly" error.
Windows XP Service Pack 3.
On a different computer, I get an error pointing to
nvtt.dll instead of
kernel32.dll, which seems to be an Nvidia related dll, which is not surprising, because it runs on an nvidia graphichs card.
Inside a version of the game I downloaded using my friend's steam account, I managed to get a different log file with this other machine, available here.
