『VALORANT』Resolving VAN9001 and VAN9003 Errors on Windows 11

This article explains how to fix the issue where VALORANT, the tactical FPS developed by Riot Games, won't launch on Windows 11.

On October 5, 2021, Microsoft released its latest operating system, Windows 11. Many users who own compatible PCs may have already upgraded to the new OS.

However, due to increased security requirements in Windows 11, VALORANT now requires certain features—Secure Boot and TPM 2.0—to be enabled on your PC. If these are not activated, you may encounter errors such as VAN9001 or VAN9003, preventing the game from launching.

In this article, we’ll introduce the features required to run VALORANT on Windows 11 and walk you through how to enable them. If you’ve updated your OS and are having trouble starting the game, we hope this guide helps you resolve the issue.

Why VALORANT Won’t Launch on Windows 11, like TPM 2.0,Secure Boot Requirements

Reasons

With Windows 11, VALORANT has increased its security requirements and now requires two features—Secure Boot and TPM 2.0—to be enabled. If these features are not activated, the game will crash with an error message like:"This build of Vanguard requires TPM version 2.0 and Secure Boot to be enabled in order to play" along with an error code such as VAN9001 or VAN9003.

Both Secure Boot and TPM 2.0 are security features built into your PC. They help prevent the use of cheat programs, and also allow Riot Games to link hardware IDs to suspicious accounts running such programs, enabling stronger enforcement actions like account bans.

As Windows 11 gaming PCs become more common, these measures may help create a cleaner and more secure gaming environment.

Below, we’ll explain how to enable Secure Boot. We’ll skip instructions for enabling TPM 2.0, as it’s already a requirement for installing Windows 11.

Important notes:

• Secure Boot must be enabled through the BIOS menu, so if you’re unfamiliar or uncomfortable with BIOS settings, this procedure is not recommended.
• Proceed at your own risk—this guide is intended only for users who feel confident managing system settings.
• Also, enabling Secure Boot while CSM (Compatibility Support Module) is turned on may cause issues with your operating system. Make sure your system is in UEFI mode before completing the setup.
