I am former engineering professor at Polytechnic School University of São Paulo, and a mathcad heavy user since it has been launched, decades ago. Presently I own a Mathcad Prime 5.0 license. I offer private classes to engineers, and use it frequently, thus I would like to upgrade my license to the last available version. I've installed Mathcad Express Prime 8.0 - 30 days evaluation. What is the best condition and the procedure to have a definitive license? Thanks.
