Best Possible Solution for Vanguard Error Code VAN-81 in 2XKO
The Vanguard error with code VAN-81 indicates an issue with the Vanguard anti-cheat, which prevents it from launching. If the anti-cheat doesn’t load, the game won’t run. It is possible that the anti-cheat files got corrupted or didn’t install correctly in the first place. There isn’t a mechanism to reinstall the Vanguard anti-cheat.
However, if you delete all the anti-cheat files, it triggers the launcher to download the files again. Follow these steps to delete Vanguard anti-cheat to trigger a reinstallation:
- Go to the “C:\Program Files\” directory in Windows Explorer.
- Next, delete the “Riot Vanguard” folder.
- Next, go to the Recycle Bin and delete the “Riot Vanguard” folder from there as well.
- Now, restart your PC once.
- Next, launch 2XKO from the launcher again, and it will trigger the reinstallation of the Riot Vanguard anti-cheat.
