NOTE: You will lose access to online multiplayer by doing this.

If you're reading this guide odds are you want to be able to run Max Payne 3 without the Rockstar Games Launcher or Social Club either because you're using Linux, a 32bit version of Windows or simply because you don't want to deal with any of Rockstar's bullshіt.
For that, we're going to downgrade our game to the last version before the RSGL update.

Moving on to what we actually want, we need to download the binaries for the old version of Max Payne 3 from HERE:
https://sharemods.com/24el603ngu91/MaxPayne3_Remove_Social_Club_v2.7z.html

NOTE: Due to v3 triggering anti-virus detections and causing some scare I have reverted the link back to the older v2, which shouldn't trigger any detections[www.virustotal.com], however, v2 causes the game to crash whenever you start New Game+.
If for some reason you want v3, you may check the Wayback Machine[web.archive.org]
Most of the detections[www.virustotal.com] for v3 are either from no-name anti-viruses or caused by AI triggers (which aren't perfect)

After you're done downloading, extract the files, you should see a new folder in the location where you extracted the files, copy everything inside it.

Now we need to browse to our Max Payne 3 install directory. A easy way to find it is right click Max Payne 3 in your library and then click Manage > Browse local files. Now double-click the Max Payne 3 folder.

Now you have to copy the files you have extracted to the Max Payne 3 folder, replace everything when prompted to.
Then you right click install.bat and run it as administrator. If everything went right, you should now be able to launch the game without installing Social Club and the Rockstar Launcher.

Copy all the files extracted to the Max Payne 3 folder and replace everything when asked.
Now you want to open a terminal window in the Max Payne 3 folder, you want to run install.sh by entering:
You probably want to delete your current proton prefix for app id 204100 if you already had installed Social Club and the Rockstar Games Launcher.
Now you should be able to launche the game if everything is right.

If the game worked without any issues then congratulations, you're now running Max Payne 3 without any of Rockstar's trash in your computer.
If you have any problems then please feel free to ask whatever you have to ask in the comments section, I will try to aid you if I'm able to.
