You can only get it through beam dog. There is no steam version, gog etc etc.
There is a lot of people having issues with trying to get it to start. I am sorry that you are having this issue as I am using a win7 64bit system and the game is working fine with mine.

It might not be the trainer that is causing the issue. The game seems to be bugged for many people. Please confirm there is no crashes when playing without the trainer.
lol I know. I was meaning to the others. May bad for the mix up bro.
