Battlefield 6 players are facing multiple technical problems such as the REDSEC error, Secure Boot not enabled, and Anti-Cheat launch errors. These issues often prevent the game from starting or cause it to crash on launch. Here’s a complete and easy guide to fix them quickly.
1. What Causes the Battlefield 6 REDSEC Error?
The REDSEC error usually appears when the game’s anti-cheat system detects security conflicts on your PC. It can be caused by:
- Disabled Secure Boot or TPM 2.0 in BIOS.
- Corrupted or outdated EA AntiCheat files.
- Third-party software interfering with Battlefield 6’s startup process.
Don’t worry—these issues can be resolved in just a few steps.
2. Enable Secure Boot and TPM 2.0 in BIOS
Battlefield 6 requires Secure Boot for its anti-cheat protection. Follow these steps to enable it:
- Restart your PC and enter the BIOS menu (press F2, F10, or DEL depending on your motherboard).
- Go to the Boot section.
- Set Boot Mode to UEFI.
- Enable Secure Boot.
- Navigate to the Security tab and ensure TPM 2.0 is enabled.
- Save changes and restart your PC.
After rebooting, launch the game again to check if the REDSEC error is gone.
3. Repair or Reinstall EA AntiCheat
Sometimes, the EA AntiCheat system becomes corrupted and prevents Battlefield 6 from starting. To fix this:
- Open the EA App or Steam library.
- Locate Battlefield 6.
- Click on Manage → Locate Game Files.
- Find the EA AntiCheat folder.
- Run EAAntiCheat.exe and select Repair.
If the issue persists, uninstall and reinstall EA AntiCheat completely.
4. Verify Battlefield 6 Game Files
Missing or damaged files can trigger Secure Boot or AntiCheat errors. Here’s how to verify and repair them:
- On EA App:
- Go to My Library.
- Right-click Battlefield 6 and select Repair.
- On Steam:
- Open Properties → Installed Files.
- Click Verify Integrity of Game Files.
This will replace any broken or missing files automatically.
5. Disable Conflicting Third-Party Software
Background software like MSI Afterburner, RivaTuner, Discord overlay, or VPN clients can interfere with Battlefield 6. To prevent this:
- Close all overlay or monitoring tools.
- Disable unnecessary startup programs.
- Reboot your PC before launching the game.
After that, run Battlefield 6 as an administrator.
6. Update GPU Drivers and Windows
Outdated drivers or pending Windows updates can cause launch or anti-cheat errors.
- Open Device Manager → Display Adapters → Update Driver.
- Visit the official NVIDIA, AMD, or Intel website for the latest drivers.
- Run Windows Update and install all critical patches.
Keeping everything updated ensures Battlefield 6 runs smoothly with anti-cheat compatibility.
7. Reinstall Battlefield 6 (Last Resort)
If none of the methods work, a clean reinstall can fix hidden conflicts:
- Uninstall Battlefield 6 via EA App or Steam.
- Delete any leftover folders from:
Documents\Battlefield 6C:\Program Files\EA Games\Battlefield 6
- Reinstall the game fresh.
After installation, launch it with Secure Boot enabled and AntiCheat repaired.
Conclusion
Battlefield 6 REDSEC, Secure Boot, and Anti-Cheat errors can be frustrating, but following these fixes step-by-step will help you get back into the action fast. Start by enabling Secure Boot and verifying your anti-cheat installation. Once resolved, your game should launch without any further issues.
