Open your antivirus settings and look for Quarantine or Protection History .
The error is a common headache for Far Cry 3 players, often occurring because the game cannot locate a critical component of the Ubisoft Game Launcher. This file is a Dynamic Link Library (DLL) that helps the game communicate with Ubisoft's DRM and online services.
Since this DLL is part of the Ubisoft Game Launcher API, a corrupted launcher installation is often the culprit. Modern versions of the game use (formerly Uplay).
Whether you're dealing with a fresh installation or a sudden crash after an update, here is how you can fix the error and get back to Rook Islands. 1. Check Your Antivirus Quarantine
If you see ubiorbitapi_r2_loader.dll listed, select Restore .
Add the Far Cry 3 game folder as an "Exclusion" or "Exception" in your antivirus settings to prevent it from being deleted again. 2. Reinstall Ubisoft Connect (Uplay)
