Riot Vanguard triggers the “Incompatible Software Component Detected” error when it identifies a running background program, overlay, or third-party driver that violates kernel security policies or contains known vulnerabilities.

Step 1: Close Blacklisted Apps and Overlays

  • Terminate memory and debugging utilities like Process Hacker, Cheat Engine, or x64dbg.

  • Disable system injectors and visual mods such as MacType, ReShade, or custom mouse-mapping tools.

  • Exit background overlay apps, including RivaTuner Statistics Server (RTSS), Overwolf, and EVGA Precision X.

Step 2: Update or Uninstall RGB Utilities

Outdated motherboard and RGB controller drivers (such as ene.sys or legacy CPU-Z/HWMonitor driver hooks) are frequent targets of Vanguard flags.

  • Update ASUS Armoury Crate, MSI Center, Gigabyte Control Center, and Corsair iCUE to their latest software versions.

  • If updates do not clear the flag, temporarily uninstall your RGB lighting software.

Step 3: Clean Boot Windows

  1. Press Win + R, type msconfig, and press Enter.

  2. Open the Services tab, check Hide all Microsoft services, and click Disable all.

  3. Locate vgc (the Riot Vanguard service) in the remaining list and re-check its box so it stays active.

  4. Navigate to the Startup tab via Task Manager, disable non-essential startup items, and restart your computer.

Step 4: Reinstall Riot Vanguard

  1. Right-click the Vanguard icon in your system tray and select Exit Vanguard.

  2. Open Windows Settings > Apps > Installed Apps.

  3. Search for Riot Vanguard and click Uninstall.

  4. Restart your computer, launch the Riot Client, and start Valorant to automatically download and re-install Vanguard.

If the error continues after these steps, open Command Prompt as Administrator and run sfc /scannow to fix any corrupted Windows system files interfering with Vanguard’s signature checks.
