How To Fix Error VAN 57 In League of Legends

League of Legends players sometimes run into Error VAN 57, an issue that can stop the game from launching or kick you out before you even reach the client. This error is usually tied to Riot Vanguard, the anti-cheat system that runs in the background and is required for the game to work properly. When something goes wrong with Vanguard, League of Legends won’t start as expected, which can be frustrating, especially if you’re trying to jump into a ranked match or play with friends. In this guide, we’ll break down what Error VAN 57 actually means, why it happens, and the most reliable ways to fix it so you can get back into the game without unnecessary hassle.

What Causes Error VAN 57 in League of Legends?

Error VAN 57 in League of Legends is almost always linked to Riot Vanguard not running the way it should. Vanguard is the anti-cheat system that starts with your computer, and if it’s disabled, blocked, or fails to launch properly, the game won’t let you in. One of the most common causes is Vanguard being turned off in Windows services or not starting automatically after a system reboot. This can happen after Windows updates, driver changes, or even crashes. Another frequent reason is antivirus or firewall software interfering with Vanguard, either by blocking its service or preventing it from running in the background. In some cases, Error VAN 57 can also appear if Vanguard files are corrupted, outdated, or not installed correctly, which usually happens after a failed update or an incomplete installation. Less commonly, system settings like Secure Boot being disabled or conflicts with other low-level software can also trigger the error, stopping League of Legends from launching until Vanguard is fully functional again.

How to Fix League of Legends Error VAN 57

Fixing Error VAN 57 in League of Legends usually comes down to making sure Riot Vanguard is installed correctly and running the way it’s supposed to. The first thing to try is a simple PC restart, since Vanguard is designed to start with Windows and sometimes fails to load after updates or long uptime sessions. If the error still shows up, open the Windows Services menu, find vgc, and make sure it’s set to Automatic, then start the service manually if it isn’t already running. Another reliable fix is reinstalling Riot Vanguard entirely: uninstall it from your system, restart your computer, launch League of Legends, and let the client reinstall Vanguard automatically. You should also check your antivirus and firewall settings, as some security programs block Vanguard by default, so adding Riot Vanguard and League of Legends as exceptions can prevent conflicts. If none of that works, make sure Windows is fully updated and that Secure Boot is enabled in your BIOS, since Vanguard relies on certain system-level protections to function properly. In most cases, one of these steps will resolve Error VAN 57 and allow the game to launch normally again.
