  • This error is common among Windows 11 users, especially people who have issues regarding their BIOS (Basic Input/ Output System).
  • To fix this, you may apply multiple solutions, such as enabling Windows Secure Boot or running Valorant on Compatibility mode. For detailed and effective solutions, follow our guide below.
  • To prevent this Valorant error, we need to ensure that the BIOS (Basic Input/ Output System) is running on the “UEFI” mode. Furthermore, it should have the configuration which is required by Valorant’s anti-cheat.

Causes for the VAN 9003 Error

There are several reasons this would occur, most of which are related to the Firmware of your Windows 11. The causes mentioned below are the most common amongst the Valorant users encountering this error.

Windows Secure Boot

The BIOS (Basic Input/ Output System) is responsible for the configuration and security of your Device. Windows has introduced various options in the BIOS which ensure the Operating System’s security. One of these is “Windows Secure Boot“. Riot Vanguard, which is Valorants anti-cheat system, automatically denies your Windows from playing Valorant if you have this option disabled.

BIOS (Basic Input/ Output System) Mode

Windows has made various modes for your BIOS (Basic Input/ Output System), such as CSM (Compatibility Support Module), Legacy, or UEFI (Unified Extensible Firmware Interface). Valorant requires the “UEFI” BIOS mode in Windows 11 to function properly. Therefore, if you are using any other mode other than UEFI on your Operating System, you would face this Valorant error.

Outdated Operating System

As Valorant is a relatively new Video-game, it only supports new operating systems such as Windows 11 and the latest version of Windows 10. If you play on older Operating Systems, for example, Windows 8.1 or Windows 7,  you may encounter this error code. Therefore, it is vital to ensure that you are running the latest release of your OS (Operating System).
