Well, I installed in on my PC, and it was fine.
So I left the CD-ROM in my PC drive, mapped the drive to my laptop, and then installed it over the network. Worked like a charm. The best part is that this version is No CD (4.32). When did that happen? 4.30? I haven't played in a while.
And now that I have GOTY edition, I'll have to say don't bother. It's not worth the extra 15 bux if you have broadband and you're short on dough. As far as I can tell, all it is is the standard Unreal Tournament with a couple of extra splash screens, Inoxx and Rocket Arena and Chaos. But the last two are not even in the main install. So basically you're paying the extra bux just to save on download headache (which is fine for me).
Anything else I'm missing? These instructions are pretty sparse as far as the installation goes.
