In this guide, we will tell how to resolve the Riot anti-cheat service error and fix Vanguard error VAN 128 in League of Legends.
Encountering the League of Legends Vanguard Error VAN 128 can be frustrating for players, as it prevents access to the game due to issues related to Riot Games’ anti-cheat software, Vanguard. This error usually arises when your system’s security settings are out of sync with what Vanguard requires, or when conflicting software is installed.
What Is Vanguard Error VAN 128?
The Vanguard Error VAN 128 occurs when Riot’s Vanguard anti-cheat software detects an issue with your computer’s security configuration or conflicts with other software. Vanguard is essential to maintaining the integrity of the game by preventing cheats, but it can sometimes flag legitimate system settings or software as problematic, leading to this error.
How to Fix League of Legends Vanguard Error VAN 128
Here are the steps you need to take to resolve this issue and ensure that your system meets Vanguard’s security requirements.
Confirm Device Is in a Trusted/Secured State
One common cause of League of Legends Vanguard Error VAN 128 is a mismatch in system security settings. Specifically, Vanguard checks if Test Signing Mode is disabled and Driver Signing Enforcement is enabled. If either of these settings is incorrect, Vanguard won’t allow you to run the game.
To fix this, press the Windows key and type “cmd.” When the Command Prompt appears, right-click and select “Run as administrator.” In the Command Prompt window, enter the following commands one by one, pressing Enter after each:
bcdedit /set TESTSIGNING off
bcdedit /set nointegritychecks OFFAfter executing both commands, restart your computer. These commands ensure that your system is in a secured state, which should resolve the Vanguard VAN 128 error if security settings were the issue.
Disable Debug Memory Dump
In some cases, an issue with Windows’ default debugging settings can trigger Vanguard Error VAN 128. Changing the debug settings might help to fix the problem. Start by pressing the Windows key and typing “sysdm.cpl,” then press Enter. This will open the System Properties window. Navigate to the Advanced tab and under the Startup and Recovery section, click on Settings. In the Write debugging information dropdown, select “(none)” and then restart your computer.
This adjustment ensures that your system’s debugging setup isn’t interfering with Vanguard’s processes, potentially resolving the error.
Uninstall Fasoo Software
If you find yourself stuck in a loop where you keep reconnecting to League of Legends without an error message or solution, the Fasoo software could be the root cause. Fasoo is a digital rights management tool that sometimes conflicts with Vanguard.
To remove it, press the Windows key, type “Control Panel,” and open it. Go to Programs > Programs and Features and look for any software published by “fasoo.com.” Once located, click on it and select “Uninstall.” After removing the software, restart your computer and check if the error has been resolved.
Disable or Uninstall CryptoPro Cloud CSP
Another possible conflict arises from CryptoPro Cloud CSP, which often causes Vanguard Error VAN 128. If CryptoPro is installed on your system, you may see it running as “cpinit.exe” in the Task Manager.
To address this issue, open the Control Panel, go to Programs > Programs and Features, and find CryptoPro Cloud CSP. Click on “Change,” and in the pop-up window, click Next, then select Change again. Under the Compatibility section, check the box labeled “This component will be unavailable.” After making these changes, restart your computer.
If the issue persists, you may need to fully uninstall CryptoPro from your system. To do this, go back to the Programs and Features section in Control Panel, select CryptoPro Cloud CSP, and click Uninstall. Restart your computer after the uninstallation and check whether Vanguard is now functioning correctly.
Riot Anti-Cheat Service Error Fix
The League of Legends Vanguard Error VAN 128 can be caused by a variety of system settings or software conflicts. By confirming your device is in a trusted state, disabling debug memory dump, and removing conflicting software such as Fasoo or CryptoPro Cloud CSP, you can typically resolve the issue. If these steps do not work, consider reinstalling Vanguard or League of Legends as a last resort.
