How to fix
Valorant VAN9003 error
on Windows

Hello. When I try to launch Valorant on my Windows PC, I get the VAN9003 error. Is there a way to fix it?

When TPM (Trusted Platform Module) 2.0 and Secure Boot are not enabled on a user's device, a recurrent problem known as the VAN9003 error appears in Valorant on Windows. This error manifests as an obstacle to launching the game, with players encountering messages such as:

This build of Vanguard requires secure boot to be enabled in order to play

or:

Initial attestation failure: Secure boot requirement not met.

The core issue is that Valorant requires the activation of both Secure Boot and TPM 2.0 due to its special requirements on Windows 11. When certain security elements aren't enabled, Valorant has problems launching, which results in the VAN9003 issue. This error could result in crashes while trying to enter the main menu in addition to preventing the game from launching.

The annoying inability for users to enjoy Valorant on their Windows 11 devices is the result of this issue. The error disrupts the gaming experience, causing inconvenience and frustration among players who are eager to engage in the game but are prevented by the VAN9003 error.

To resolve this issue, make sure the Windows 11 device has both TPM 2.0 and Secure Boot enabled. However, despite the straightforward nature of the solution, users may face challenges in navigating these settings, especially if they are not familiar with BIOS configurations.
