SIf you've already enabled Secure Boot and are still encountering the VAN9003 error, there might be a few more things to check:
If the issue persists, please consider submitting a ticket to Riot Games support for more personalized assistance.
- **Check BIOS Mode**: Ensure your system is using UEFI mode and not Legacy BIOS. Secure Boot only works with UEFI. You can check this in the System Information app on Windows (Type `msinfo32` in the Run dialog).
- Verify Secure Boot Status: Confirm Secure Boot is indeed enabled. Sometimes, changes in BIOS settings need saving before exiting.
- Update Windows: Ensure your Windows OS is fully updated. Some updates might be necessary for Vanguard to recognize Secure Boot.
- Check Trusted Platform Module (TPM): Enable TPM if itβs disabled. Secure Boot sometimes requires TPM to be active.
