Thanks again. I downloaded and reinstalled BDE 5.11. I noticed also that there is a 5.2 version but didn't want to try just yet. After reinstalling BDE, the problem still existed; so much for my theory.
Still bent on getting IC running again, I tried the install process a couple of times from Safe Mode with the same results. I assume this would rule out a conflict with another application in memory that would be causing the problem. However, on my third attempt I reinstalled the 1.5 version of IC and it finally worked again.
I still want to get IC v.2.5 working again but the only thing I can pinpoint at this point is that it may have something to do with the .dbf extension since it cannot find Result.dbf even if it's physically there.
I'll keep trying but any input on your side would be appreciated.
