Where to download? (Mafia 2)

Hello.
Not thought today was to find the original Mafia 2 hard.
A few years ago, you could find a clean game, which it was possible to put update 2 or 5, as desired.
Now find some Repack.
The problem is that I want to run the seventh trainer, and he's looking for mafia2.exe. There it is, but the game runs not through it.
Can you please tell me where to get a Repack where mafia2.exe or even better, the original.
Thanks in advance!
