Anti-cheat & online services
Easy Anti-Cheat, BattlEye, Vanguard and other anti-cheat or online service errors that block a game from starting.
- BattlEye error in Arma Reforger: how to fix "Failed to install BattlEye Service"Arma Reforger uses the BattlEye anti-cheat service, and when the game cannot install or start it, the game closes at launch or shows "Failed to install BattlEye Service". The most common cause is a broken BattlEye install in the game folder, so verifying game files and then reinstalling BattlEye with the bundled scripts is the usual fix. These steps come from community sources, not from BattlEye or Bohemia Interactive documentation.
- BattlEye error in DayZ: how to fix service, driver and kick messages"BattlEye error" in DayZ is a family of messages, not one fault. Some mean the BattlEye service can't install or start on your PC, others are server kicks. Verifying game files, clearing the BattlEye service folder and checking antivirus exceptions solves most of the first group.
