Step 1: Restart the BattleEye Service Manually

The BattleEye service might not have started correctly. Restarting it manually can often fix the error.

Why this matters: Sometimes the service might stop or fail to start automatically. Manually restarting ensures it’s running before the game attempts to use it.

Step 2: Verify Game Files Integrity

Corrupted or missing game files can cause BattleEye to fail. Verifying the game files through your game launcher helps fix these issues.

Here is how to do it for Steam:

  1. Open the Steam client and go to your Library.
  2. Right-click on the game that uses BattleEye and select Properties.
  3. Go to the Local Files tab.
  4. Click on Verify Integrity of Game Files.
  5. Wait for the process to complete, then restart your computer.
  6. Try launching the game again.

Why this matters: Missing or damaged game files can prevent BattleEye from loading correctly, so this step ensures all files are intact.

Step 3: Reinstall BattleEye Service

If restarting the service doesn’t help, reinstalling BattleEye can fix installation issues.

  2. Open the BattleEye folder inside the game directory.
  3. Run the Uninstall_BattleEye.bat file by double-clicking it. This will remove the current BattleEye installation.
  4. Next, run the Install_BattleEye.bat file to reinstall the service.
  5. Once completed, restart your PC and try starting the game again.

Why this matters: A fresh installation of BattleEye removes corrupted files or faulty settings that cause startup failures.

Step 4: Check for Windows System File Corruption

  1. Press Windows + S, type cmd, right-click on Command Prompt, and select Run as administrator.
  2. In the Command Prompt window, type the following command and press Enter:
  3. sfc /scannow
  4. Wait for the scan to complete. It will automatically repair corrupted files if found.
  5. Restart your computer and test the game again.

Why this matters: System File Checker fixes damaged Windows files that could block BattleEye from starting.

Step 5: Adjust Windows Defender and Firewall Settings

Windows Defender or other firewalls might block BattleEye from running. You can add exceptions to avoid this.

  3. Scroll down to Exclusions and click Add or remove exclusions.
  4. Click Add an exclusion and select Folder.
  5. Browse to your game’s BattleEye folder and add it.
  6. Next, open Windows Defender Firewall from the Control Panel.
  7. Click Allow an app or feature through Windows Defender Firewall.
  8. Find your game and BattleEye service and make sure they are allowed on both private and public networks.
  9. Save the changes and restart your PC.

Why this matters: Firewall or antivirus software blocking BattleEye prevents it from starting, so exclusions ensure it runs smoothly.

  1. Right-click your game’s shortcut or .exe file and select Properties.
