If your problem sounds like this, you're in the right place:

  • VAN MISSING -117: Vanguard is required to be running.
  • What does VAN Missing -117 error mean?
  • My game crashed and I got error VAN Missing -117.

Resolution

VAN Missing -117 usually means Riot Vanguard isn’t running, and since it’s required for your game to run properly, your client will close automatically.

Try these steps in order. We’ll start with the quickest fixes first, then move into the bigger ones if Vanguard still needs a little help getting back online. Launch your game after each step to see if it worked.

  1. Restart your PC. This gives Vanguard a fresh startup and can resolve many temporary Vanguard startup issues.
  2. Reinstall Vanguard. This refreshes Vanguard directly without requiring you to reinstall the whole game. Follow our guide to manually uninstall Vanguard, restart your PC, then launch your game again to reinstall Vanguard.
  3. Perform a clean boot. Background apps or services may interfere with Riot Vanguard, and a clean boot helps you dial in on what exactly is giving you trouble.
  4. Reinstall your game. This can replace corrupted or missing game files that may be preventing Vanguard or your game from launching correctly. Follow our guide to uninstall and reinstall your game.

If you still see the error after trying these steps, submit a ticket to Player Support. Make sure you attach your logs so we can take a closer look and help get you back in the game.
