How do you install and activate this program? I have never received a product number and can't get a hold of anyone from PTC for tech support. This is a joke!
So you bought Mathcad (Prime) Student edition (56 bucks for one year of usage).
Have you tried installing it?
If no: do!
If you did: Where's the problem?
This .PDF is for Prime 2.0.
I assume that the same procedure works for Prime 4...?
