We have an installer template (the aip file) that we modify via command line to add prerequisites and other things to customize the installer for each configuration we need to deliver. This all works fine except that the boostrapper defaults to FULL UI, which we do not want. I need to be able to set the bootstrapper ui level to "Basic UI and progress" via command line. How can I do this and if it isn't supported what do you recommend as a work around?
