How to Fix Valorant Error Code 57: Detailed Guide

Valorant players sometimes run into Error Code 57, an issue that prevents the game from launching or connecting properly. This error is almost always related to Riot Vanguard, Valorant’s anti-cheat system, which needs to be running correctly in the background for the game to work. When Vanguard fails to start, gets blocked, or isn’t installed properly, Valorant immediately throws Error Code 57 and stops you from playing. In this quick guide, we’ll explain what Error Code 57 actually means, why it happens, and the fastest, most reliable ways to fix it so you can get back into the game without wasting time.

What Causes Error Code 57 in Valorant?

Error Code 57 in Valorant almost always points to a problem with Riot Vanguard, the game’s required anti-cheat system. The most common cause is Vanguard not running in the background, which often happens if its services were disabled manually or failed to start after a system reboot. Since Valorant cannot launch without Vanguard active, the game immediately blocks access when this occurs. Another frequent trigger is interference from third-party software, especially antivirus programs, firewalls, or system optimization tools that mistakenly block Vanguard from operating correctly. Corrupted or missing game files can also lead to Error Code 57, usually after an interrupted update or an incomplete installation. In addition, outdated Windows versions or old hardware drivers can cause compatibility issues that prevent Vanguard from initializing properly. In most cases, the error isn’t tied to your account or the Valorant servers, but rather to system-level issues that stop Vanguard from running as intended.

How to Fix Valorant Error Code 57

If you’re getting Error Code 57 in Valorant, the good news is that most fixes are simple and don’t take long. Start with the basics before moving on to deeper troubleshooting. First, fully close Valorant using Task Manager, restart your computer, and then launch the game again. This alone often fixes temporary conflicts between Riot Vanguard and your system. If the error comes back, check for third-party software conflicts. Antivirus programs, firewalls, and PC optimization tools are known to interfere with Vanguard, so temporarily disable them and try launching the game. If Valorant works after disabling one, that software is likely the cause and may need to be uninstalled or properly excluded.

If the issue persists, reinstalling Riot Vanguard is one of the most reliable fixes. Open the Windows Run menu, go to Programs and Features, uninstall Riot Vanguard, then restart your PC. After rebooting, launch Valorant and let Vanguard reinstall automatically, making sure it’s allowed to start with Windows. System-level problems can also trigger Error Code 57, so updating your graphics drivers and system drivers is important. Use Device Manager to check for updates, and visit your GPU manufacturer’s website to install the latest drivers directly if needed.

For compatibility-related issues, running Valorant in compatibility mode can help on some systems. Right-click the Valorant shortcut, open Properties, go to the Compatibility tab, and try running it under an older Windows version like Windows 8. You should also make sure Windows itself is fully up to date, since missing or paused updates can prevent Vanguard from functioning correctly. Finally, if none of these steps work, reaching out to Riot Games Support is the best move. Submitting a support ticket allows their team to look at your logs and system details and give you a fix tailored to your setup, which usually resolves stubborn cases of Error Code 57.
