You may see a VAN restriction error when trying to launch Valorant, especially if you use an older version of Windows. Riot’s anti-cheat system, Vanguard, now enforces stricter operating system requirements, which can block access even for legitimate players.
Although Valorant officially supports Windows 10 build 19041 and newer, some players report this error despite meeting those minimum specifications. Understanding what triggers the Windows build restriction and how to address it can help you regain access and get back into the game.
How to Fix Valorant VAN Restriction Windows Build Error?
You cannot bypass this restriction with a simple setting change. Riot has confirmed that upgrading your Windows version is the only reliable fix for the VAN Restriction Windows Build error.
If you still run an outdated or unsupported Windows build, update your system immediately. In most cases, moving to Windows 11 resolves the issue because it meets Riot Vanguard’s current security standards.
Follow these steps:
- Open Settings > Windows Update.
- Check for available feature updates.
- Install the latest supported Windows version.
- Restart your PC after installation completes.
After upgrading, you must enable specific security features. Vanguard requires hardware-backed protections to function properly.
Make sure you enable:
- TPM 2.0 (Trusted Platform Module)
- UEFI Secure Boot
Access these options through your motherboard BIOS or UEFI firmware settings. Save your changes before exiting.
This error can also appear if your system contains vulnerable drivers capable of low-level memory access. Outdated or insecure drivers may trigger Vanguard’s protections. Updating Windows typically removes or blocks these risks.
You should also:
- Update all chipset and motherboard drivers
- Remove unused or suspicious kernel-level software
- Reboot before launching Valorant again
Do not rely on firewall exceptions or temporary workarounds. Vanguard checks system integrity at launch, and unsupported builds will continue to fail validation.
Once you upgrade Windows and enable TPM 2.0 and Secure Boot, relaunch Valorant. The game should pass Vanguard’s checks and allow you to log in normally.
