The Prime2 conversion does not see that I have MathCAD 15 installed ... Is there somewhere the path needs to be set? I clearly have 15 running and use it.
Are You sure that You have the latest maintainance release of Mathcad 15?
Prime2 conversion does only work with Mathcad 15 M010 (not M005 or F001).
Waht version of Mathcad 15 are you using?
