If you have a CD with the card, try letting Windows search it out. Open the Device Manager, right click the entry for the sound card, and choose "Update Driver..." and point it to the CD. It ought to pull the INF/SYS/ect files right from the disk and install them for you.
They won't be "up to date" so much as the latest online installer, but only the system drivers will be installed that way.
I ended up doing just that, followed by running the online installer (hot tip: the 55mb pack for Audigy/Live cards isn't WHQL signed!). That generated two blue-screens of death; one while running Quake 4, and another two hours after I uninstalled it. Both times Windoze said it didn't know what caused the unrecoverable error. So I let Windoze update nab the Audigy driver that M$ had, which changed my Audigy card to a Live card in the Device Mangler.
I heard the rumors, I watched the stars align, and I figured I might get lucky by going Creative instead of onboard sound. Especially since this is a new build system (E7500 on a P5Q Turbo, Radeon 4670) and I know Intel-based systems get a little performance boost using a dedicated sound card. But if I get another BSoD I'm ripping the card out, and VIA be damned, I'll use the onboard audio. At least it works.
Now if I could just get my frakkin' Orange Box to install over this dial-up connection...
