- Check the Vanguard service. Open the Windows Services app, find
vgc, and set its startup type to Automatic. Restart the PC if you change the setting. Do not apply this instruction if Vanguard Pre-Check is configured to enable Vanguard on demand. - Restart the PC. If
vgcwas already set to Automatic, restart Windows to give Vanguard a fresh startup, then try launching the game. - Reinstall Riot Vanguard. Manually uninstall Vanguard, restart the PC, and launch the game so Vanguard can reinstall. Check the game again after the installation.
- Try a clean boot. A background app or service may be interfering with Vanguard. Perform a clean boot to help isolate that conflict, then launch the game. If it works, investigate which disabled app or service caused the issue before restoring your usual startup configuration.
- Reinstall the game. Riot says reinstalling may replace corrupted or missing game files that prevent Vanguard or the game from launching. Try launching the game after reinstalling.
If VAN 57 still appears
If the error remains after the troubleshooting steps, submit a ticket to Riot Player Support and attach logs. Include that you are seeing VAN 57 and which steps you completed so support can see what has already been tried.
