Trying to launch Valorant but stuck with the message: “We couldn’t install a required dependency. Please try again, restart your computer, or reach out to our player support team”?

This frustrating error usually means Riot Vanguard, Valorant’s anti-cheat service, isn’t working correctly. The good news? You can fix it in a few simple steps.

Why This Matters

Valorant won’t run without Riot Vanguard. If it’s disabled, corrupted, or misconfigured, the game won’t launch. Fixing this error ensures:

• Riot Vanguard loads properly at startup

• Valorant can launch without interruptions

• Your system stays compatible with anti-cheat checks

Step 1: Enable Vanguard Services

If Vanguard isn’t set to run automatically, Valorant won’t start. Here’s how to fix it:

1. Press Windows + R, type services.msc, and hit Enter.
   

2. Find vgc in the list of services.

3. Right-click → Properties.
   

4. Set Startup type to Automatic.

5. Click Start under Service status.

6. Hit Apply → OK.
   

7. Restart your PC.

Step 2: Edit Registry Settings

A wrong registry entry can block Vanguard. Resetting it restores default behavior.

⚠️ Caution: Always back up your registry before editing.

1. Press Windows + R, typeregedit, and hit Enter.
   

2. Navigate to:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CI\Policy


3. On the right, locate DevOverrideEnable.

4. Double-click → Set Value data to 0.

5. Click OK, close the editor.
   

6. Restart your PC.

Step 3: Reinstall Vanguard Using Command Prompt

If Vanguard files are corrupted, a clean reinstall usually fixes the issue.

1. Search for Command Prompt → Right-click → Run as Administrator.
   

2. Stop Vanguard services by entering:

   sc stop vgc
   sc stop vgk

3. Delete Vanguard with:

   sc delete vgc
   sc delete vgk

   

4. Restart your PC.

5. Open the Riot Client – it will automatically reinstall Vanguard.

6. Restart once more to activate Vanguard.

Common Mistakes to Avoid

• Forgetting to run Command Prompt as Administrator → Commands will fail.

• Skipping restarts → Vanguard won’t reload correctly.

• Editing the wrong registry key → Can cause system instability.

Extra Tips

• If these fixes don’t work, try reinstalling the Riot Client entirely.

• Make sure your Windows version is up-to-date.

• Disable third-party antivirus temporarily, as it may block Vanguard.

FAQs

Yes, if you only change the DevOverrideEnable key as instructed. Always back up first.
