The .exe might be different if it's a 64-bit version. All of the trainers we create are for 32-bit versions of the game. Some of them may work in 64-bit mode, but the exe will typically have to be the same.

I'm having the same trouble in a 32bit version of vista ult. I have used your trainers in the past and found them great, this one just doesn't want to say (h)activated. Demo version I'm using is 1.0.0.1
Hope this helps in some way
