I would like to install the CityEngine silently in our classroom. Starting with the /S command line option will run the silent install but the installation of vcredist_x64_vc10 is not started properly from the main installer. It still needs user input, it looks like the wrong command line options have been used to trigger this installation. If this vcredist_x64_vc10 was already installed then the installer will start in repair mode.
It would be even better to hava an MSI installer.
