1. What Is VAN 1067 in League of Legends?

VAN 1067 is an error code generated by Riot Vanguard, the anti-cheat software used for both League of Legends and Valorant. The error means Vanguard failed to initialize—which in plain English usually means something in your system is blocking Vanguard or making it crash on startup.

You’ll typically see this error right as you try to open League of Legends, and you’ll be kicked out with a message like:

“We couldn’t install a required dependency”

or

“Something went wrong during installation.”

It’s not a League bug—it’s Vanguard refusing to launch.

2. Why Does VAN 1067 Happen?

There’s no single cause for VAN 1067, but Riot has officially listed it under issues caused by “unusual software” or incompatible drivers. Based on real player reports, the most common reasons include:

Security features like TPM 2.0 or Secure Boot being disabled in BIOS

Unusual or unauthorized third-party software like:

• Dante Controller (Audinate)
• Windows Remote Desktop
• Some VPN or remote-access tools

Corrupted Vanguard service or Riot Client installation

Outdated BIOS or missing system files

What Players Are Saying

One Reddit user shared this fix:

“Turns out this was due to the driver mdnsNSP.dll crashing. This driver is related to Dante Controller. Uninstalling that program fixed the error instantly.”

Another said:

“I removed Windows Remote Desktop completely. Rebooted. Error gone.”

This confirms what Riot hinted at: some programs install low-level drivers that interfere with Vanguard, and Vanguard doesn't like surprises.

3. How to Fix VAN 1067 in League of Legends (2025 Guide)

Step 1: Reboot Your PC

Yes, it sounds obvious, but Riot Support officially recommends it as the first step. Sometimes Vanguard simply doesn’t launch properly and needs a clean boot.

Step 2: Uninstall Conflicting Software

Based on user feedback, uninstall these if you have them:

• Audinate’s Dante Controller
• Windows Remote Desktop
• Any remote-access tools or virtual machines (VMWare, Parsec, etc.)

Step 3: Enable TPM 2.0 and Secure Boot

This is crucial if you're running Windows 11.

• Reboot your PC and enter BIOS (usually F2, Del, or Esc)
• Find “Security” or “Boot” tab
• Enable TPM 2.0 and Secure Boot
• Save and exit

This ensures Vanguard’s integrity check passes on startup.

Step 4: Run System Updates

• Install all Windows updates
• Update your BIOS (check your motherboard’s official site)
• Install or repair Visual C++ Redistributables

Step 5: Reinstall Vanguard

If none of the above works:

1. Uninstall Riot Vanguard from Windows Apps
2. Restart your PC
3. Launch League again—it’ll auto-install Vanguard fresh

Bonus: Check for Background Services

Press Ctrl+Shift+Esc, go to the Startup tab, and disable suspicious entries or tools you don’t recognize.

4. What is Vanguard Error VAN 57 in League of Legends?

VAN 57 means Riot Vanguard is not running or failed to initialize when you launched League of Legends.

What causes it?

• Vanguard was not started automatically when your PC booted.
• Riot Vanguard service was disabled or corrupted.
• You may have manually exited Vanguard before launching the game.

How to fix it:

Restart your PC (this is often enough to restart Vanguard properly).

Make sure Riot Vanguard is set to start automatically:

• Press Windows + R, type services.msc, press Enter.
• Find vgc, right-click → Properties → Set to Automatic → Click Start.

Reinstall Riot Vanguard:

• Uninstall Vanguard via Windows Settings.
• Restart your PC.
• Launch League of Legends again—it will reinstall Vanguard.

5. What is Vanguard Error VAN 135 in League of Legends?

VAN 135 typically means your system is having trouble communicating with Riot’s servers, even though Vanguard is running properly.

What causes it?

• Firewall or antivirus software blocking Vanguard or Riot Client.
• Network instability (e.g., bad DNS, VPN conflict, or ISP throttling).
• Riot’s servers may be temporarily down.

How to fix it:

1. Restart your router and PC.
2. Add Riot and Vanguard to your firewall and antivirus exceptions.
3. Try changing your DNS (e.g., use Google DNS: 8.8.8.8, 8.8.4.4).
4. Temporarily disable your VPN or switch servers.
5. Check Riot’s server status: https://status.riotgames.com/
