This is a mod for GTAIV, which allows it to run properly with Windows 8.
This mod is also compatible with Windows 7 or Vista!
The package contains:
*Essential update for GTAIV for Windows 8
*Windows 8 compatible launcher
*Maximum Graphics (Depends on your Graphics Card and CPU)
1)Run the update to remove Rockstar Games Social Club.
2)Put all the files from the "essentials" in the root folder.
If you get an error: "Securom Launcher: Failed to start application " replace "LaunchGTAIV.exe" in the root folder with the one from the "Windows 8" one.
If you're not using Games for Windows Live, then add in the root folder the "xlive.dll" from the "Windows 8" folder.
If you get some fatal errors (WS10 for example) try google to find fixes. All of them work.

I have Windows 8 and vanilla game works fine for me. So what does this do exactly?
