[Solved] VGC Error 1: Incorrect Function (Riot VanGuard Service)

Posted by

Lately, I can’t run my game Valorant. There’s an error message saying “VANGUARD NOT INITIALIZED” when I trying to enter the game. At the first glance, I know I can easily fix it by enabling the VGC service but there’s another error that will show “ERROR 1: Incorrect Function”.

After hours of trying, I finally found the solution. *This said solution will work in all Windows OS Versions.

  1. Uninstall VGC Service.
    Go to C:/Program Files/Riot Vanguard/vgc.exe and run the uninstaller.
    Just wait until the uninstallation is finalized.
