'TrueOS Desktop' installer loops endlessly, never succeeds in completing the installation

I am trying TrueOS , the evolution of PC-BSD . I downloaded the 'TrueOS-Desktop-2016-09-09-x64.iso'. When running the installer in Parallels Desktop 12.0.1 virtual machine the main menu for the installer appears, with a few options to choose from. I let that menu expire after about several seconds to auto-boot. I see all the installer scripts reporting to the console. But then the main menu for installer re-appears, deja-vu. Lather, rinse, repeat. The **main menu and installer scripts keep running in a loop**, endlessly. I never get any further than seeing the installer scripts console output fly-by, never see any success in booting the TrueOS environment. Any suggestions?
