Well, I got the KB on 1603 installer errors, but I was running into a bunch of problems with that routine (mainly locked out files I was trying to take ownership). Since this computer in question is my "play" computer and does not have valuable information to keep, I did a clean install of the OS, got it all updated and then put the Roxio Easy CD and DVD Burning software back to work. Everything is great now. The OS on this old machine has been in place for 8 years or so, so it was time to freshen it up a bit. It's a Dell Dimension 8300 running XP. It's hardware checked out good, but it did need an OS renewing. Thanks for offering your advice.
