Audigy 2 CD won't install

[morphine]

Hey there.

I've recently discovered the joys (and sorrows) of nLite and started to slipstream my Windows XP CDs with hotfixes, drivers, etc. I've also, naturally, removed much of the unnecessary Windows XP crud. After a couple false starts (such as mistakenly removing OpenGL, CHM support, some IE stuff, etc), I've gotten a pretty solid installation.

However, there's one thing that's still bugging me: the Audigy 2 CD. You see, even though Creative provides updated drivers to download, I still need the applications from the CD, most notably Mixer, Speaker Settings, EAX Console, and the all-important Equalizer.

The specific problem: pull up the Audigy 2 CD, hit "Install", and the Installshield window that pops up does nothing and immediately says it's done, hit Finish, thank you very much . Has anyone come across this situation, or something similar? Is there also any way to track what Installshield's trying to do?
