Install trainer in Bioshock 2 directory. Create shortcut on the desktop.Enable the trainer.Go to windows games.locate Bioshock exe.Right click. Run in directx 9.
Before doing this I had problems with this trainer.More than a few functions didn't work. Now it works perfectly.
My version of Windows 7 is 64 bit.

Worked for me right off the bat, though i cant remember if i activated at the main menu or while in game.
