    Requirements


    A LEGAL COPY OF THE GAME, FROM STEAM, OR ROCKSTAR WAREHOUSE (Social Club version)

    We do NOT support ILLEGAL copies of the game. GT-MP Will NOT work on illegal copies. Buy the game.


    In order to run Grand Theft Multiplayer you will need the following requirements installed to ensure compatibility:

    1. Visual C++ 2015 Redistributable (x86 and x64) (Direct download links: https://download.microsoft.com…5925B00/vc_redist.x86.exe and https://download.microsoft.com…5925B00/vc_redist.x64.exe)
    2. Visual C++ 2013 Redistributable (x86 and x64) (Direct download links: http://download.microsoft.com/…CD5CD6E3/vcredist_x86.exe and http://download.microsoft.com/…CD5CD6E3/vcredist_x64.exe)
    3. .NET Framework 4.6.2 or newer


    Alternatively, you might have to enable .NET Framework manually. You can do this by following these steps:

    1. Navigate to your control panel
    2. Click on Programs
    3. Click on Turn Windows features on or off
    4. Check all boxes with .NET Framework in them
    5. Hit OK


    Make sure your Windows is updated to the latest version.


    Verifying your game files

    For Steam users:

    1. Navigate to your Steam library
    2. Right click on Grand Theft Auto V and click on Properties
    3. Click on the Local Files tab
    4. Click on Verify integrity of game cache



    Cleaning up your game


    In case that you got any mods installed: GT-MP might not be compatible with certain mods and the game may crash or not run at all. Try to remove any mods except GT-MP or reinstall your game to make sure you got a clean GTA V installation.


    Reinstalling Grand Theft Multiplayer

    Reinstalling the entire client can serve as a solution. When reinstalling Grand Theft Multiplayer make sure to install it under the following conditions:

    • Do not install Grand Theft Multiplayer in your GTA V directory or in your GTA V directory within a folder
    • Reinstall Grand Theft Multiplayer into an user folder, like C:\Users\<your username>\GT-MP (important for the cases that GT-MP starts the game in singleplayer)
    • Run GrandTheftMultiplayer.Launcher.exe as administrator

    You can save this setting by right clicking on the launcher executable file, selecting properties and then select the Compatibility tab. At the bottom you can check the Run as administrator option to force it to run as administrator every time you run it.


    Disabling third party programs

    Any kind of software, firewall or overlay can be the cause of instability and crashes. These include but are not limited to:

    • Overlays such as Steam Overlay, Overwolf, Fraps, MSI Afterburner, RivaTurner, SweetFX and so on
    • Antivirus software such as McAfee, Malwarebytes, Windows Defender and so on
    • Disable or add an exception to your firewall for GT-MPSubprocess.exe
