You shouldn't have to install Physx anything as it should have been installed at the same time as the game was installed from the game disk or ISO if a digital download.

Only reason I can see for it to not install is if there was an option to install it when installing the game, and it was declined. Or it isn't a legal version of the game.

Thats correct as I didn't install Physx when i installed Mafia 2 as the option was unticked and I wasn't sure, but when I went to launch the game it installed then on its own and all works fine.
