I tested the Live Installer from CD but it only starts fine when booting in "full version". In "basic" it doesn't start. Running the script from terminal it shows several "import errors" starting with "gtk" "gtk-glade".
Thanks for the report. We've known that one though. In basic mode, the libraries that are need to run the live installer are just not there. Same for lilosetup. My proposal is to remove support for booting in basic and core modes using the live CD. The option to install a basic or core system will still be there of course.
