If you’ve ever seen Vanguard Error VAN 57<\/strong> in League of Legends<\/em>, you know how frustrating it can be when you’re ready to play but can’t even launch the game. This error pops up when Riot Vanguard\u2014the game’s required anti-cheat system\u2014fails to start properly. The good news is that this is usually fixable with a few straightforward steps.<\/p>\n

Why Does VAN 57 Happen?<\/h2>\n

Error VAN 57 means Vanguard isn’t running<\/strong> when the game tries to launch. Since Vanguard is mandatory for playing League of Legends<\/em>, the client blocks you from starting a match until the anti-cheat service is active. Here’s what typically causes it:<\/p>\n

    \n
  • Vanguard service disabled or stopped<\/strong>: The background service (called VGC) isn’t set to start automatically or got turned off<\/li>\n
  • Corrupted Vanguard files<\/strong>: Incomplete updates or file corruption prevent proper initialization<\/li>\n
  • Registry conflicts<\/strong>: Windows registry settings interfering with Vanguard’s startup<\/li>\n
  • PC hasn’t been restarted<\/strong>: Vanguard sometimes needs a fresh boot to load correctly<\/li>\n<\/ul>\n

    Most of the time, you can solve this in just a few minutes. Let’s walk through the fixes.<\/p>\n

    Fixes You Can Try<\/h2>\n

    1. Restart Your PC and the Riot Client<\/h3>\n

    Start with the simplest solution\u2014restart both your computer and the Riot Client<\/strong>. This forces Vanguard to reload from scratch and clears any temporary conflicts. After rebooting, open the Riot Client and try launching League of Legends<\/em> again.<\/p>\n

    If that doesn’t work, move on to the next fix.<\/p>\n

    2. Enable and Start the VGC Service<\/h3>\n

    The VGC service is Vanguard’s background process. If it’s disabled or stopped, the game won’t launch. Here’s how to fix it:<\/p>\n

      \n
    • Press Win + R<\/strong>, type services.msc<\/code>, and press Enter<\/li>\n
    • Scroll down and find vgc<\/strong> in the list<\/li>\n
    • Right-click it and select Properties<\/strong><\/li>\n
    • Change Startup type<\/strong> to Automatic<\/strong><\/li>\n
    • Click the Start<\/strong> button under Service status<\/li>\n
    • Press Apply<\/strong>, then OK<\/strong><\/li>\n
    • Restart your PC so Vanguard starts automatically<\/li>\n<\/ul>\n

      This ensures Vanguard runs every time you boot up. Launch the game again to see if VAN 57 is gone.<\/p>\n

      3. Fix the DevOverrideEnable Registry Entry (Advanced)<\/h3>\n

      If the VGC service fix didn’t work, a Windows registry setting might be blocking Vanguard. The DevOverrideEnable<\/strong> entry controls security overrides\u2014if it’s set to 1<\/strong>, it can prevent Vanguard from initializing. Here’s how to fix it:<\/p>\n

        \n
      • Press Win + R<\/strong>, type regedit<\/code>, and press Enter<\/li>\n
      • Navigate to: HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\CI\\Policy<\/code><\/li>\n
      • On the right side, find DevOverrideEnable<\/strong><\/li>\n
      • Double-click it and change the Value data<\/strong> to 0<\/strong><\/li>\n
      • Click OK<\/strong> and close the Registry Editor<\/li>\n
      • Restart your PC<\/li>\n<\/ul>\n

        Try launching League of Legends<\/em> again. If the error still appears, move to the final fix.<\/p>\n

        4. Uninstall and Reinstall Vanguard<\/h3>\n

        If none of the above worked, Riot Vanguard itself might be corrupted. A clean reinstall removes broken files and resets everything. Here’s how to do it:<\/p>\n

          \n
        • Press Win + R<\/strong>, type appwiz.cpl<\/code>, and press Enter<\/li>\n
        • Find Riot Vanguard<\/strong> in the list, right-click it, and select Uninstall<\/strong><\/li>\n
        • Restart your PC<\/li>\n
        • Open the Riot Client and launch League of Legends<\/em> (Vanguard will reinstall automatically)<\/li>\n
        • If prompted, allow Vanguard to install and restart your PC again<\/li>\n<\/ul>\n

          After the reinstall completes, the game should launch without issues.<\/p>\n

          What NOT to Do<\/h2>\n

          When troubleshooting VAN 57, avoid these common mistakes:<\/p>\n

            \n
          • Don’t disable Vanguard permanently<\/strong>\u2014the game requires it to run, and you’ll just see the error again<\/li>\n
          • Don’t skip the PC restart<\/strong>\u2014Vanguard often needs a fresh boot to load correctly<\/li>\n
          • Don’t manually delete Vanguard files<\/strong>\u2014always use the proper uninstall process through Windows<\/li>\n<\/ul>\n

            When to Contact Riot Support<\/h2>\n
