When you start the game, a message appears that says the compability of the graphic card is tested. Do you have a GeForce higher than the 6600 series, the game won't start. That's because JoWood has stopped making patches/updates/downloads at a certain moment. I Industry Giant 2 Tycoon fan has made a patch. With this update, the game wil work on Windows Vista. You can dowload the update on several torrentsites.
