The “Secure Boot needs to be enabled to launch FACEIT AC” error appears when Secure Boot is disabled or your PC runs in Legacy BIOS mode. FACEIT Anti-Cheat requires UEFI mode with Secure Boot enabled.
Check the current state
Press Win + R → msinfo32.
Make sure:
BIOS Mode = UEFI
Secure Boot State = On
If it’s set to Legacy, switch to UEFI and enable Secure Boot.
Enable Secure Boot
Enter BIOS (Del, F2, or Esc).
In the Boot / Security section, set Secure Boot = Enabled.
If the option is grayed out, disable CSM.
Save changes (F10) and restart the system.
In BIOS, choose Factory Keys or Reset to default keys.
Verification
After restarting, open msinfo32 again — the Secure Boot state should be On. FACEIT AC should now launch without issues.
Conclusion:
To fix this problem, enable UEFI mode, turn on Secure Boot, and reinstall the anti-cheat if needed. This FACEIT requirement helps protect CS2 from cheats and ensures proper anti-cheat functionality.
