SDK 18 no longer supports spaces in project path and gives an error (first screenshot - red message). It seems to distribute the path over several parameters? This can be solved by changing the project path so that it does no longer contain spaces.
Furthermore SDK 18 wants to launch the simulation using a splash screen I have not seen before the latest updates (second screenshot). The attempt runs into an error (third screenshot).
Nevertheless fspackagetool seems to compile all right (again third screenshot) but the console window does not close before the error message has be confirmed with the green ok-button.
They’re working on it!
