If your FACEIT Anti-Cheat client fails to start, displays error codes, or sits silently without launching, this guide provides tested working fixes for Windows 10 & 11 systems.
1. Core System Requirements for FACEIT AC
Modern FACEIT Kernel Anti-Cheat enforces 4 mandatory hardware & firmware security checks:
- UEFI Boot Mode (Legacy / CSM must be disabled)
- Secure Boot — Enabled with default keys
- TPM 2.0 — Enabled (Intel PTT or AMD fTPM)
- Hardware Virtualisation — Enabled (Intel VT-x or AMD SVM)
2. Checking System Status in Windows (msinfo32)
Press Win + R, type msinfo32 and hit Enter. Inspect two critical rows:
- BIOS Mode: Must state UEFI. If it says Legacy, your boot drive uses MBR partition scheme.
- Secure Boot State: Must state On.
3. Configuring BIOS Settings Step-by-Step
Reboot your PC and repeatedly press Del, F2, or F10 to access BIOS setup.
Step 1. Enable UEFI Mode
Navigate to Boot menu -> set Boot Mode to UEFI and disable CSM (Compatibility Support Module).
Step 2. Enable Secure Boot
Under Security or Boot menu, set Secure Boot to Enabled. If greyed out, set Secure Boot Mode to Custom and choose Restore Factory Default Keys.
Step 3. Enable TPM 2.0
- For Intel CPUs: Enable PTT (Platform Trust Technology).
- For AMD CPUs: Enable fTPM (Firmware TPM).
Step 4. Enable CPU Virtualisation
Go to Advanced -> CPU Configuration -> Enable Intel VT-x or AMD SVM Mode.
4. Quick Troubleshooting Checklist
