I hear you. I am honestly grasping at straws at this point. Do you perhaps know who owns the rights to mathcad now?
The software was bought by PTC and so they have the rights. They decided to develop a new version on a more modern code base - good idea, unfortunately very badly implemented and last year they decided to stop selling the legacy version. But of course they still own the rights to legacy Mathcad (except for the symbolic engine muPad).
I was talking of a possible private individual who bought a single user perpetual license (maybe in the days when Mathsoft were the owners of Mathcad) and maybe is willing to it sell along.
But it sure would be not that easy to find that person.
And if, its not clear if selling along the license was allowed by the licensing terms.
And if, its not clear if PTC would feel obliged and willing to create a new license file for you.
Therefore, I think that the probability of being able to legally get hold of a working old Mathcad version is very very small.
Maybe @DJNewman can shed some light on the license conditions and the possibility to generate a new license file in case you manage to acquire an old Mathcad version transferred. But, since he works in marketing, he'll probably wants to persuade you to rent Prime 8 for a year ;-). A perpetual version is not offered and so you would have to pay money year after year just to get access to your own intellectual property.
