help me guys : VAN Restrictions
Error: VAN IOMMU Restriction (sometimes VAN -102 as well)
• Systems tested:
My account fails to launch Valorant on multiple PCs in my gaming center.
• Other accounts on the same PCs work perfectly fine without errors.
• This shows the problem is not hardware or BIOS related, but specifically tied to my account
What I have tried:
• Enabled all BIOS security settings (VT-d/IOMMU, Secure Boot, TPM, DMA).
• Verified Windows settings (Secure Boot = On, VBS/HVCI = Running, Kernel DMA = On).
• Reinstalled Vanguard multiple times.
• Updated BIOS and all chipset/GPU/LAN drivers.
• Tested the account on PCs where other accounts work fine.
I am attaching:
• Screenshot of the VAN error.
• Screenshot of msinfo32 (showing Secure Boot, VBS/HVCI, Kernel DMA = On).
• Details of my motherboard (MSI Z790 Carbon WiFi II, latest BIOS).
Thank you for your assistance.
Best regards,
