VAN 57 usually means Riot Vanguard is not running or could not start correctly. Start by checking the Vanguard service and restarting your PC; if that does not clear the error, follow Riot’s sequence to reinstall Vanguard, test with a clean boot, and reinstall the game. Try the game after each applicable step.
What VAN 57 means
Riot Games Player Support describes VAN 57 as a Vanguard startup issue: “VAN 57 usually means Riot Vanguard isn’t running or couldn’t start correctly.” It is a VAN error, not a VAL error. Riot lists the two code families separately in its Vanguard error-code directory and directs players to guidance for the specific code.

Work through these steps in order. Launch the game after each step that applies so you can tell whether the error is resolved before making further changes.

1. Check the Vanguard service
- Press
Windows + R, enterservices.msc, and press Enter to open the Services console. - Find the service named
vgc(Riot Vanguard). Open its properties and set Startup type to Automatic. - If you change the setting, restart your PC, then launch the game.
Exception: Do not change the service to Automatic if Vanguard Pre-Check is configured to enable Vanguard on demand. Riot’s guidance identifies that configuration as an exception to the Automatic startup instruction.

2. Restart your PC
If vgc was already set to Automatic, restart the PC anyway. A fresh startup gives Vanguard another chance to start correctly. Then launch the game and check whether VAN 57 remains.
3. Reinstall Riot Vanguard
If restarting does not help, manually uninstall Riot Vanguard, restart the PC, and launch the game. Riot says launching the game triggers Vanguard to reinstall. Check the error again after the reinstall completes.

4. Try a clean boot
Background applications or services can interfere with Vanguard. A clean boot starts Windows with a reduced set of startup apps and services, which can help isolate whether background software is involved. Follow Microsoft’s current instructions for performing a clean boot, then launch the game. If the error disappears, investigate startup apps and services to identify the conflict before returning to your normal startup configuration.
5. Reinstall the game
If VAN 57 persists, reinstall the game. Riot notes that this may replace corrupted or missing game files that prevent Vanguard or the game from launching. Launch the game after reinstalling and check whether the error is gone.
