Well if he's got a 64 bit Vista it most definitely will not work. Tried the demo of 2097 I downloaded of CNET (After a quick Google of it) and it doesn't work.
zer0shen, do you have Vista 32 bits? If you have 64 bits, I'm interested to know your configuration, because Compatibility mode did not work (Said I needed to find the 64 bit application and use it instead of the 32 bit). I have Windows Vista Home Premium 64b.
