Update fail

This great game ran fine on my old XP setup, but after installing Vista I can't even boot up the game. It just says that the program stopped working/answering, or something like that (it's a Danish Vista, so I'm not quite sure what to translate it to)

Blitzkrieg 2 is not working on Vista.
Says after installing that version to create subdirs not compatible is with Vista.
Than i tried running it on mij old pc and its not worth looking at.
Blitzkrieg 1 was great but 2 is not worth buying it.

si se jeu marche sous vista , ji est moi meme jouer mai a la suite dune erreu g tou desinstaller et je ne trouve plus le patch !! lol (blitskrieg 2 et fall of the reich)
