Why Does This Error Happen?

Before diving into fixes, it helps to understand why this happens. Unlike older games that install entirely in one folder, Watch Dogs 2 relies on two separate software entities communicating:

The Game Client (Steam or Epic Games Launcher)
The Ubisoft Service (Ubisoft Connect)

The error means that the Watch Dogs 2 executable (WatchDogs2.exe) cannot find the Ubisoft Connect launcher in your system’s registry or file paths. This is common after Windows updates, moving game folders, or installing the game on a different hard drive than your launchers.

Solution 3: Reinstall Ubisoft Connect

Sometimes the easiest fix is to let the installer sort out the paths for you.

Uninstall Ubisoft Connect from your Control Panel.
Go to the official Ubisoft website and download the latest version of Ubisoft Connect.
Install it. During installation, ensure you install it to the same drive where your Watch Dogs 2 game files are located.
Once installed, restart your PC and try launching the game again.
