I need help installing the drivers and software.

I'm having a lot of trouble installing the drivers for the Fab@Home Model 1. I'm very familiar with Windows but I can't figure out how to install this. The wiki tells me to point the Hardware Update Wizard to the unzipped driver files in the folder FAHDRV. I have done this over and over and it keeps telling me Windows isn't finding any driver files in the folder. What am I doing wrong?
