Usage between Mathcad prime and mathcad express?

[Sweiler]

Quite a lot of our work can essentially be done with the free/express license of MathCAD.

1. Can we, with Express versions, view and partially-manipulate workbooks created with Prime versions?

1. If I, in Prime, create a solve block in a workbook, can someone in Express open that sheet and change the input variables?

1. Can users switch b/w Prime and Express versions easily?

1. Ideally, carrying on the same use-case, if I’m manipulating a workbook from express version but see I want to make a change by using a Prime-only feature, can I click a button to grab the license and unlock the Prime functions?

Point by point:
1, Yes, but as soon as a recalculation that involves a 'premium' feature is required, you will get a red.
1. Yes, but see point 1 above.
1. You can have different versions of Prime side by side on the same computer. That includes Express. But I don't think you can have Prime 5 and Prime 5 Express on the same computer. ( unless multi-boot).
IF....you own a license it is easy to switch from Express to full Prime. To switch back would probably require reinstall or you'd Have to invalidate the license file.
1. See point 1 above.

Success!
