Check-out the Zabaware Troubleshooting:
http://www.zabaware.com/assistant/trouble.htmlEven if you don't see your exact problem, there are other methods of installation listed, I would try one of those. If you are trying to install from a CD-ROM then I think that making a flat copy of your CD-ROM to your hard drive would be what I would try next. I have seen similar problems with other types of software bombing-out at the end of an install process when installing from a CD-ROM. I think that making a copy of the CD-ROM to the hard drive is actually a fairly common fix that often works for many different types of software and/or computer systems. It has worked for me in the past with other software titles. In general, it is a problem of hardware and software not working together properly during the install process, so by elimitating the cd-rom hardware as part of the install process often is the key to a complete install on certain systems for certain software.
Good Luck!
