Latest News About Vanguard Error Van 57

Here’s the latest snapshot I can share about Vanguard error VAN 57.

• What VAN 57 means: It’s a Vanguard anti-cheat service startup issue that prevents League of Legends (and some Riot games) from launching, often described as Vanguard not starting correctly. This aligns with common troubleshooting threads that people run into when the anti-cheat component fails to initialize.[2][5]

• Common causes you’ll see in recent guidance:

  • Vanguard services (VGC or VGK) not running or being blocked by security software.[5]
  • Conflicts with antivirus/firewalls or Windows security settings, sometimes related to driver signing or secure boot state.[6][2]
  • Network or system state quirks (DNS/Winsock, clean boot state) used to isolate interference.[2]
  • Occasional reports that a full system reboot or even a power-cycle reset helps re-establish a clean start of Vanguard after prior errors.[3]

• Typical steps suggested by recent guides and posts:

  • Ensure Vanguard services are running and set to automatic startup, then restart the Riot Client and the PC.[5][6]
  • Whitelist Vanguard components in antivirus/firewall, and temporarily disable conflicting security tools during startup if safe to do so.[2][5]
  • Check Windows 10/11 for system integrity issues (sfc /scannow, DISM/RestoreHealth) and apply any pending system updates or driver updates, especially for graphics hardware.[5]
  • If secure boot or test-signing mode is involved, adjust those settings to a standard secure boot state and disable test signing mode if enabled.[7][2]
  • Perform a clean boot to identify software conflicts that might be blocking Vanguard from starting.[2]

• Public guidance tone in the most recent online chatter:

  • Many users report success with a sequence like: restart Riot Client and PC, verify Vanguard services are running, temporarily disable conflicting antivirus/firewall rules, then re-enable after launch; some also report success after DNS/ Winsock resets or a full client reinstallation.[8][9][5]

• Notable caveats:

  • Since VAN 57 is tied to how Vanguard initializes on a given machine, results can vary widely based on OS version, security software, and driver configuration. If you continue to see VAN 57 after standard fixes, Riot Support with logs and diagnostic steps is often advised.[5][2]

Would you like me to tailor a step-by-step checklist for your setup (Windows version, antivirus, and whether you use Secure Boot)? If you share that, I can assemble a precise, minimal sequence to try first. I can also help find official Riot Support guidance or recent user reports specific to your hardware.
