Running TeamSpeak as Administrator

If you run TeamSpeak 3 as admin, Overwolf must also be run as admin.
Any mismatch may prevent the Overwolf TS plugin from connecting properly.

Important:
If you launch a game as administrator, Overwolf may not be able to inject the TS overlay.

League of Legends Notifications

Notifications are disabled by default in LoL.
Follow the notification steps below and uncheck “Don’t show notifications when playing League of Legends” if you want them enabled.

TeamSpeak Won’t Inject Into the Game / Overlay Not Working

The most reliable way to get TS3 working with Overwolf is to:

  1. Make sure your game is supported by Overwolf. 

  2. Verify that Overwolf is running.

  3. Launch your game.

  4. Confirm that Overwolf has injected (Alt+Tab → look for the Overwolf dock).

  5. Open the Overwolf TeamSpeak app to launch TeamSpeak 3 from there.

This ensures both apps are synced and injected correctly.

Can’t See TeamSpeak Notifications In-Game

Check your notification settings:

  1. Right-click the Overwolf tray icon.

  2. Open Settings.

  3. Go to the Notifications tab.

  4. Make sure all checkboxes under the In-game column are checked.

League of Legends Note

Notifications are off by default.
Uncheck “Don’t show notifications when playing League of Legends” if you'd like to see them.
