How to Fix VAN Restriction Error on HVCI (Memory Integrity) – Full Guide

How to Fix VAN HVCI Restriction Error in Valorant – Step-by-Step Guide

If you’re a gamer running Windows 10 or Windows 11 and suddenly got hit with the “VAN restriction” error due to HVCI, you’re not alone. This pesky issue usually pops up when you’re trying to play Valorant or other games that depend on Vanguard Anti-Cheat by Riot Games. But don’t worry — we’ve got a complete step-by-step fix right here to help you get back into your games fast.

🎮 What is the VAN Restriction HVCI Error?

The VAN restriction error related to HVCI (Hypervisor-Enforced Code Integrity) usually looks like this:

“Your account does not meet the following requirements…”

This message appears when your system fails to meet security standards required by the anti-cheat system — specifically HVCI (Memory Integrity) must be enabled and supported on your machine.

Vanguard, the anti-cheat system used in games like Valorant, checks your system for HVCI support to ensure a secure environment. If it detects that your system does not have the correct security settings, it blocks the game from launching.

🔧 How to Fix the VAN Restriction Error Step by Step

Before we dive in, here’s a quick safety note: If you’re not confident about editing system settings or BIOS, back up your files or create a restore point.

✅ Step 1: Check HVCI Support on Your PC

1. Press Windows + R on your keyboard.
2. Type msinfo32 and hit Enter.
3. Scroll down to check these two fields:
   • Virtualization-based security → Should say “Running”
   • Device Guard → Should be “Enabled”

If these are not enabled, you’ll need to turn on virtualization in BIOS.

🔁 Step 2: Enable Virtualization in BIOS

1. Restart your PC and enter the BIOS/UEFI (usually by pressing Delete, F2, or F10 during boot).
2. Locate Virtualization Technology (VT-x/AMD-V) and enable it.
3. Save and exit the BIOS.

Once virtualization is on, HVCI will be supported.

🔐 Step 3: Enable Core Isolation & Memory Integrity

1. Open Windows Settings (Windows + I)
2. Go to Privacy & Security > Windows Security > Device Security
3. Click on Core Isolation Details
4. Turn on Memory Integrity

⚠️ This feature prevents malicious code from being injected into secure processes. It’s critical for games that use anti-cheat systems like Riot Vanguard.

5. Restart your computer.

🛠️ Step 4: Enable HVCI via Group Policy (Advanced Method)

For users with Windows 10/11 Pro, you can take it a step further:

1. Press Windows + S and search for Edit Group Policy
2. Navigate to:

   Computer Configuration > Administrative Templates > System > Device Guard
   

3. Double-click on Turn on Virtualization Based Security
4. Set it to Enabled
5. Click Apply > OK

This ensures HVCI is always enabled across reboots.

🚀 Step 5: Update Drivers

Make sure all your system drivers are up to date — especially:

• Graphics card (NVIDIA/AMD/Intel)
• Motherboard chipset
• BIOS firmware

Outdated drivers can conflict with security features like HVCI and cause errors.

You can use:

• Device Manager (devmgmt.msc)
• Official software like GeForce Experience, AMD Adrenalin, or your motherboard’s support site

🔄 Step 6: Restart & Launch Your Game

After completing all the above steps:

1. Restart your PC to apply all settings.
2. Launch your game (like Valorant).
3. The VAN HVCI restriction error should now be gone!

🧠 Why This Fix Works

The HVCI restriction error is triggered when your PC doesn’t meet the security baseline for trusted game environments. Riot’s Vanguard is especially strict with these requirements, enforcing HVCI to block kernel-level cheats.

By enabling:

• Virtualization in BIOS,
• Core isolation via Windows Security, and
• Group Policy enforcement,

you ensure your PC is in full compliance with the game’s anti-cheat security model.

🧩 What If You Still See the VAN Restriction?

If you’ve followed every step and still see the error:

• Double-check virtualization is enabled in BIOS.
• Use msinfo32 again to verify status.
• Make sure Secure Boot is also enabled in BIOS.
• Reinstall Riot Vanguard by uninstalling and reinstalling the game.

🛠 Tip: You can also try running a system scan using sfc /scannow in Command Prompt (admin) to fix any corrupted system files.

📌 Final Thoughts

The VAN HVCI restriction error might seem like a showstopper, but it’s actually quite fixable. With a few system tweaks and driver updates, you can get back to gaming smoothly without any interruptions.
