How to Fix Valorant Error Code VAN 9001 (TPM 2.0 Secure Boot Glitch)

by

Valorant Error Code VAN 9001 is a common system security error that prevents the game client from initializing on Windows machines. This issue occurs because Riot Games’ Vanguard anti-cheat software requires both Trusted Platform Module (TPM) 2.0 and Secure Boot to be actively running in your motherboard’s firmware settings before it will allow the game to boot.

Whether this block is caused by an outdated BIOS configuration or deactivated security partitions inside your hardware registry, you can fix it. Follow this step-by-step troubleshooting guide to bypass error VAN 9001 and secure your system.

Common Causes of Error VAN 9001

  • Disabled UEFI Secure Boot: Your system firmware is set to legacy CSM mode instead of modern UEFI security standards.
  • Inactive TPM 2.0 Chipset: The physical or firmware-based security validation module is turned off in your BIOS layout.
  • Conflicting Exploit Protection Settings: Local Windows security parameters blocking Vanguard from reading hardware states.

Method 1: Enable TPM 2.0 and UEFI Secure Boot in BIOS

  1. Restart your computer, and as it boots back up, tap the Delete key or F2 key repeatedly until your motherboard BIOS interface opens.
  2. Switch to Advanced Mode (usually by pressing F7), then navigate to the Security or Boot tab.
  3. Locate Secure Boot, change the setting from Disabled to Enabled, and ensure the mode is set to Standard.
  4. Navigate to the Advanced/Peripherals tab, look for AMD fTPM switch or Intel PTT (Platform Trust Technology), and change it to Enabled.
  5. Save your changes and exit (usually by pressing F10), then let your computer boot to Windows normally.

Method 2: Adjust Windows Exploit Protection Parameters

  1. Click your Windows Start menu, type Exploit protection, and open the system settings window.
  2. Select the Program settings tab at the top of the interface.
  3. Click Add program to customize and choose Add by exact file name.
  4. Type vgc.exe (the Vanguard service application) and click Add.
  5. Scroll down to Hardware-enforced Stack Protection, check the box to override system settings, toggle it Off, and apply the changes.
