Valorant error code VAN 9001 appears when your Windows 11 system doesn't meet the game's security requirements, specifically TPM 2.0 (Trusted Platform Module) and Secure Boot. This error prevents you from launching Valorant as Riot's Vanguard anti-cheat system requires these security features to be enabled.

How to Fix Error Code VAN 9001

  1. Check Current TPM and Secure Boot Status

  2. Enable TPM 2.0 in BIOS/UEFI

    Changing BIOS settings incorrectly can prevent your system from booting. Only modify settings you understand, and note down original values before making changes.

  3. Enable Secure Boot

    Ensure your Windows installation uses UEFI boot mode before enabling Secure Boot, or your system may not start properly.

  4. Convert to UEFI Boot Mode (if needed)

    Back up important data before converting boot modes. This process modifies your system's boot structure and could cause data loss if interrupted.

  5. Verify Changes and Test Valorant

When to Call a Professional

Frequently Asked Questions

What is TPM 2.0 and why does Valorant need it?
TPM 2.0 is a security chip that stores cryptographic keys and helps prevent cheating software. Valorant's Vanguard anti-cheat requires it to ensure a secure gaming environment and detect unauthorized modifications.
Will enabling Secure Boot affect other games or programs?
Most modern games and programs work fine with Secure Boot enabled. However, some older software, custom drivers, or dual-boot configurations might have compatibility issues. You can usually disable it temporarily if needed.
My motherboard doesn't have TPM 2.0 hardware, what can I do?
Many modern motherboards support firmware-based TPM (fTPM for AMD or PTT for Intel) that works the same way. Check your BIOS for these options. If unavailable, you may need to upgrade your motherboard or purchase a separate TPM module.
Can I play Valorant on Windows 10 to avoid this error?
No, Riot Games now requires Windows 11 with TPM 2.0 and Secure Boot enabled for Valorant. Windows 10 systems will encounter the same VAN 9001 error and cannot bypass these security requirements.
What if the error persists after enabling TPM and Secure Boot?
Restart your computer completely, update Windows 11 to the latest version, and reinstall Vanguard anti-cheat. If the problem continues, check if your TPM is properly initialized in Windows Security settings under Device Security.
