Mafia 2 Setup Exe !!top!! Here

Steam does not use a traditional Setup.exe in the way physical media does. However, you can find the "Steam installer stub" by navigating to: C:\Program Files (x86)\Steam\steamapps\common\Mafia II\ Note: Steam handles installation via its own client, but the legacy setup files are often extracted to a _CommonRedist folder.

GOG provides a completely DRM-free version of Mafia II. When you download the game from GOG, you receive a standalone setup.exe file that you can back up externally and install offline without needing a client launcher. Mafia 2 Setup Exe
