Norton Systemworks 2003

I’ve been having trouble installing Norton Systemworks 2003. I’ve installed on the same computer before and many others and never had problem until now. The first error I get is LiveUpdate won’t register with this product, next I get a error 12 while install norton utilities and none of the other pieces will install. What could be causing these problems? I’m using Windows XP Pro. Thansk in advance for your help in solving this problem.
