Wishbone,
It sounds very much like an error or damage to the install disk. Look at the disk closely for scratches, glitches or anything marring the surface. Damaged disks in factory packaging is not all that uncommon.
If the CD is indeed damaged, Epson may just send you a new one if you ask them. If not, go to their website and locate the drivers for that device and download them.
