Try the Properties window of the game executable, or see around the loading screen or the main menu screen. (Or contact the publisher, asking them to tell you how to find it.)

@Stuio
You need patch 1.11 last I checked, verify that your game actually patches to 1.11 or (like mine), gets hung-up on trying to detect a U.S.? North America? english install, aborts patch and then (sometimes depending on what's running) asks for a reboot to finalize patching.

So are there any way to run version 1.2?
