If you’re seeing VAN 1067 from Riot Vanguard (the anti-cheat used by League of Legends, Valorant, etc.), it typically means your system’s security settings are incompatible—particularly TPM 2.0 (Trusted Platform Module) or Secure Boot is disabled—or there’s conflicting software on your PC.
Here’s the full breakdown:
🔎 What VAN 1067 Means
Riot’s support documentation lists VAN 1067 as a Connection Error, and advises restarting your PC and the Riot Client. It also notes that unusual software could trigger this error—so if a reboot doesn’t help, scanning for malware or suspicious processes is recommended.
Esports.gg explains that this error can indicate your PC is infected, or that Vanguard is detecting suspicious programs. They recommend scanning with trusted antivirus tools after a reboot.
Multiple reputable guides (e.g. PlayPlex, Backdash) agree: VAN 1067 often occurs because TPM 2.0 is disabled, which Vanguard requires to run properly.
✅ How to Fix VAN 1067
1. Restart Your PC and Riot Client
A simple reboot often clears temporary conflicts.
2. Enable TPM 2.0 (and Secure Boot) in BIOS/UEFI
This is the most common fix:
Reboot your PC and press the appropriate BIOS/UEFI key (usually F2, Delete, F10, etc.), depending on your motherboard.
Navigate to Security or Advanced settings
Enable TPM (labeled TPM, PTT on Intel, or fTPM on AMD)
(Recommended) Also enable Secure Boot, and ensure your system is in UEFI mode (not Legacy BIOS)
Save changes and exit BIOS.
Restart into Windows and try launching the game again.
Playing through this basic setup resolves VAN 1067 for the vast majority of users.
3. Check the VGC/VGS Service (Valorant)
If you’re encountering this in Valorant, ensure the VGC (Vanguard) service is running:
Press Win + R, type
services.msc, and press Enter.Locate VGC (or VGS), open its properties, set Startup Type to Automatic, and click Start if not already running. Save changes.
This can resolve error code 1067 in many cases.
4. Scan for Malware or Conflicting Software
If the error persists despite TPM and Secure Boot being enabled:
Open Task Manager and look for unknown or resource-heavy processes.
Use a trusted antivirus or anti-malware tool (e.g. Malwarebytes) to scan your system. Remove or quarantine any threats.
Some apps—like Discord, keyboard software, or virtualization tools—may interfere. Try closing them before launching the game. Perform a clean boot if needed to isolate conflicts.
5. Reinstall Riot Vanguard
If all else fails:
Uninstall Riot Vanguard via Control Panel or the Start menu.
Restart your PC.
Launch the Riot Client or Valorant—the anti-cheat will reinstall automatically.
This can resolve persistent issues without reinstalling the full game.

🔧 Quick Troubleshooting Checklist
| Step | Action |
|---|---|
| 1️⃣ | Reboot your PC and Riot Client |
| 2️⃣ | Enable TPM 2.0 (and Secure Boot / UEFI) in BIOS |
| 3️⃣ | If Valorant: 确保 VGC/VGS service is running |
| 4️⃣ | Scan for malware or close conflicting software |
| 5️⃣ | Uninstall and reinstall Riot Vanguard |
🎯 In Summary
VAN 1067 is most often due to TPM 2.0 or Secure Boot being disabled, or because Vanguard has flagged suspicious software.
Enable TPM and Secure Boot in your BIOS/UEFI — this alone resolves the issue for most users.
If that doesn’t work: check VGC/VGS service, scan for malware, uninstall/reinstall Vanguard, and close conflicting apps.
