You might be interested in this: Official PTC Mathcad 15 and Prime 1–6 End-of-Sale ...

Mathcad 15 is not for sale anymore and support has ended.

License files issued for current Prime versions are only valid for Prime version 7 and higher. They are not valid for older Prime versions and also not for real Mathcad (MC15 and before).

If you (or your customer) can proof the ownership of a perpetual license, it may be worth contacting official PTC support and see if they can be of help. No guarantee - it is quite possible that the 'help' is limited to the advice to downgrade to Prime and pay the annual fee from now on.

Have you gotten an answer on this? I have reached out to PTC and I can't get a straight answer. When I renewed this year my mathcad 15 stopped working. PTC says that there is no reason for me to install but I already have it installed, just need to open. I have hundreds of files that I need to get to. Very frustrating.
