Part 1: Understanding the VAN 9003 Error

The VAN 9003 error in Valorant generally appears as a result of system incompatibilities or security protocol issues with Riot's anti-cheat software, Vanguard. This error is particularly common on systems that do not meet the requirements for Valorant or have software restrictions in place, such as Windows 11 systems running without Secure Boot or TPM .

Key Causes of VAN 9003:

• Lack of Secure Boot or TPM 2.0 – Valorant requires systems with Secure Boot and TPM 2.0 enabled to ensure a secure environment for gaming.
• Outdated Windows Version – Using an outdated version of Windows can lead to compatibility issues with the Vanguard anti-cheat system.
• Vanguard Anti-Cheat Compatibility Issues – Vanguard requires specific system configurations and sometimes doesn’t function correctly on virtual machines or certain Windows configurations.
• Driver or System Conflicts – Issues with outdated or incompatible drivers, especially for network and security, can prevent Vanguard from functioning correctly.

Understanding these potential causes is essential in identifying the appropriate solution, which we’ll cover in the next section.
