How to Fix Valorant VAN9003 Error in Windows 11

VAN9003 is an error code that appears when launching the Valorant game. The error code is accompanied by messages like, “This build of Vanguard requires Secure boot to be enabled to play” and “Initial attestation failed: Secure boot requirement”. All these messages indicate that the computer on which you are playing this game must have Secure Boot and TPM 2.0 enabled.

Windows 11 requires some advanced technologies such as Secure Boot and Trusted Platform Module and when these features are not enabled VAN9003 is likely to occur. This means in order to fix this issue these features must be enabled. See: How to Fix Valorant TPM 2.0 Error in Windows 11 (Bypassed!).

Ensure the computer is supported with TPM 2.0

To avoid error VAN9003, TPM the device should be supported with TPM 2.0 (Trusted Platform Module 2.0). Certain devices are not compatible with this feature and if you find that this also happens with yours ask the manufacturer. First of all, check if your computer is TPM supported:

  • Press Windows and R and type tpm.msc.
  • On the Trusted Platform Module (TPM) Management on Local Computer window, go to Status section. Here you should see TPM is ready to use.
  • In the TPM Manufacturer Information, Specification Version should be 2.0.

If both TPM and Secure Boot are enabled then you will no longer encounter VAN9003 error. In case, any of them is disabled you should manually enable it to fix the problem.

TPM and Secure boot settings underly in BIOS so they can be enabled from there. Every manufacturer uses its interface for BIOS so you will need to enable Secure Boot or TPM depending on its manufacturer.
