There seems to be a big problem for Mathcad users, now that Windows XP is disappearing into the past. Most of us have years of valuable Mathcad programs, and the only way to convert them to Prime is through a conversion utility in Mathcad 15 (instead of in Prime). But Mathcad 15 won't install easily on Windows 7 or 8 - from discussion on this site, it involves a lot of complicated and time-consuming work, with no guarantee of success.
* Inference 1: Do all your conversions now, while you still have a working version 15 on Windows XP or another older OS.
Unfortunately, I read that Prime 2.0 still lacks a large number of the features that made Mathcad 15 valuable, so your converted programs might not work in Prime.
* Inference 2: Your prior work will be useable only as long as you keep a working computer running older Windows. Clearly, that approach has a limited life.
* Inference 3: Even new work using Prime will be stunted, because it's not yet a platform for serious work.
Have I got this wrong? Is there a credible way forward, after all? Because an uncomfortable fourth inference might be that this is the end of the line for Mathcad.
