Risk level

Usually safe to check without specialist tools.

Urgency

Low

Quick answer

Riot Vanguard could not verify that your PC is ready for the game or failed while initializing (VAN 84). Install Windows updates, restart and check that the vgc service is set to Automatic.

Safety first

Stop and check this first

  • Do not disable Vanguard or use tools to hide from or trick its checks: the game does not run without Vanguard and Riot only documents reinstalling it through its own procedure. Account or penalty issues always go to Riot support.

Safe checks you can perform

  • Windows Update and restart
  • Vanguard service (vgc) set to Automatic
  • Reinstall Vanguard, then the game
  • Windows clean boot

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Riot Player Support with your logs
  • Do not attempt this professional task: Internet provider if the connection guide points to the network

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Riot Player Support with your logs

    What they doIf VAN 84 persists after every step, Riot Player Support reviews the client and Vanguard logs.

    They must show youthe ticket number and what the logs show.

    In writingthe code, the steps already done and the fix or next step they give.

  2. Internet provider if the connection guide points to the network

    What they doWhen Riot's connection guide does not fix VAN 84 and the fault only shows on your network, the provider checks the line and the router it supplied.

    They must show youtheir line test result.

    In writingthe incident number and what changed.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Windows Update and restart

    No special tools

    Who:
    you.
    How:
    open Settings > Windows Update, install everything available and restart the PC before opening the game.
    Result that matters:
    whether VAN 84 stops appearing with Windows up to date.
    If it stops:
    a Windows component Vanguard needs was missing.
    If it stays:
    Windows is ruled out; check the Vanguard service.
    Evidence to keep:
    a screenshot of Windows Update with nothing pending.

    Evidence: Error VAN 84

  2. Vanguard service (vgc) set to Automatic

    No special tools

    Who:
    you.
    How:
    if you do not use Vanguard Pre-Check to run Vanguard on demand, open Windows Services (services.msc), find vgc and set its startup type to Automatic; restart the PC.
    Result that matters:
    whether the game starts without VAN 84 with the Vanguard service running from startup.
    If it starts:
    Vanguard was not running when you launched the game.
    If it was already Automatic or the error stays:
    uninstall and reinstall Vanguard.
    Evidence to keep:
    a screenshot of the vgc service with its startup type and status.

    Evidence: Error VAN 84

  3. Reinstall Vanguard, then the game

    No special tools

    Who:
    you.
    How:
    uninstall Riot Vanguard manually using Riot's guide, restart the PC and open the game so Vanguard reinstalls. If the error stays, uninstall and reinstall the game too with Riot's guide.
    Result that matters:
    whether VAN 84 goes away with Vanguard at default settings or with fresh game files.
    If it goes away after reinstalling Vanguard:
    Vanguard's settings had been altered.
    If it only goes away after reinstalling the game:
    game files were corrupted or missing.
    Evidence to keep:
    the date of each reinstall and whether the error came back.

    Evidence: Error VAN 84

  4. Windows clean boot

    No special tools

    Who:
    you.
    How:
    do a clean boot (Microsoft services only, no startup programs) and open the game; then re-enable services in groups.
    Result that matters:
    whether VAN 84 goes away in clean boot and which group brings it back.
    If it goes away:
    a background app or service interferes with Vanguard; the group that brings it back points to it.
    If it appears anyway:
    rule out background programs and check the connection.
    Evidence to keep:
    the program or service that brings the error back when re-enabled.

    Evidence: Error VAN 84

What it means

Riot says VAN 84 usually means Riot Vanguard could not verify that your PC is ready to run the game or ran into an issue while initializing; the game shows it as a connection error and can kick you from a match. The code does not identify what failed: Riot orders the checks from Windows and the Vanguard service through background programs, game files and the connection.

Warnings and stop conditions

  • Mediumeditorial warning

    Do not disable Vanguard or use tools to hide from or trick its checks: the game does not run without Vanguard and Riot only documents reinstalling it through its own procedure. Account or penalty issues always go to Riot support.

    Evidence: Error VAN 84

Symptoms and causes

Probable causes · in order

  • Windows missing recent updatesPossible

    Vanguard relies on services and security changes delivered through Windows Update. Suspect it if updates are pending.

    Evidence: Error VAN 84

  • Vanguard not running when the game launchesPossible

    If you do not use Vanguard Pre-Check and vgc is not Automatic, Vanguard is not active. It is confirmed when the service shows as stopped.

    Evidence: Error VAN 84

  • Altered Vanguard settingsPossible

    Riot says to uninstall and reinstall Vanguard to restore its defaults. You can tell because the error goes away after the reinstall.

    Evidence: Error VAN 84

  • Interference, files or connectionPossible

    Background programs, corrupted game files or the network can keep the error going. Clean boot, a game reinstall and the connection guide separate them.

    Evidence: Error VAN 84
