I started the Launcher which updated to the new Launcher Version 2.0.760 automatically. As the Launcher was restarted I clicked on the Button Install MC Version 1.11.2, then the Launcher was crashed. As I tried to restart the Launcher it was funtionally and as I tried to install the new MC Version again I received the following Message.
