An old client has recently asked me to look  into a problem with an old
software I have worked on using CBuilder V3 (Pro version) back in the late
90's. Unfortunately, I cannot find my CBuilder 3 CDs; I have Cbuilder 5, as
well as manuals and even a shipping carton from V3 and V5. I also have disk
image backup of the PC that was used to work on the project. The problem
priority (and $ money the company wants to spend) is pretty low, so
conversion to V5 is probably not an option. I have previoously tried
converting to V4, but the code did not compile nd I remember that I'd have
to edit dfm fle due to some compatability issues. Is that true as far as
V3 -> V5 conversion?

Any suggestions where I can find old version CDs, or perhaps how I can
restore the image? I can probably find the receipts for the software
purchase easier than the CDs, if I need proof of purchase.
