When trying to launch the Ubisoft Game Launcher or even a game inside it, all users get an error with code 2. No solution helps, but this is because this software is no longer supported. It’s officially disabled. Ubisoft Game Launcher is replaced by a service Uplay or in other words – Ubisoft Connect. You just need to install it and sync your account with the launcher. All purchased games will instantly catch up, and the previously installed ones usually do not have to be reinstalled.
