Grand Theft Auto 4
The DRM on gta4 malfunctions on win10, rendering you unable to run the game, or login using Games For Windows Live.
I was unable to find a clean solution to this online that worked, so I installed a crack.
- download the latest version of Games for Windows Marketplace Client.
- login manually
This did not work for me.
xliveless method (inferior)
This will disable multiplayer, and mods
