Just received the full GPO, and went to install it on my home desktop (Dell, WinXP, 3GHz, 2G RAM, Gina 24/96 card, etc.). A pretty new machine.
The first disc installs just fine. The installer then asks for disc #2. I swap discs, and insert #2, click OK. The disc spins up, and after a few minutes ... spins down. Nothing more happens. If I remove the disc, the installer immediately asks me to insert disc #2 and click OK, but it never does anything else.
