Just got a new system in today. 6.4 G hardrive, a zip drive, and an 10 base T ethernet card. Windows won't install...says something about a compressed disk or a utility cache program...of which I don't think I have either. Any ideas why it won't install. Exactly the same system that I just installed windows on recently except that had a 4.3 G hardrive and no zip drive and no ethernet card.
