The installer doesn't see the second CD, but the workaround is like so. Install the 1st cd, then exit without rolling back, then mount the second cd and copy the contents of base to your hard drive. Now open a terminal and make a symbolic link from base in your harddrive to ~. This happens because the program doesn't know to search the right dir for the file, so it defaults to Y:/ for some reason, which happens to be your home dir.
When you get it to launch, notice that there's no sound. then notice that while you can move the mouse, you can't click on anything. Try to calm down, breathe deeply.
By the way, this is on a mackbook, running 10.4.9
