I've seen something similar on a machine with 256MB of ram using the 7.04 install CD. It does not produce a running system dependably, and the only time I've managed to get it to run the installer, it took ~30 minutes to respond to me clicking "OK" to select English as a language, and after several subsequent hours I still hadn't managed to select a city and hit OK. It seems the requirements for running the graphical installer is substantially over the 192MB of ram listed in the system requirements.
