If you cannot upgrade from Mathcad 15 to Prime 7, do not worry. What if I want or need to stay on Mathcad 15? Yes, Mathcad Prime 7 has been available since March 11, 2021. This FAQ will hopefully provide reassurance regarding your path forward. PTC will no longer have rights to use the third-party proprietary engine after December 31st of this year.Īs a Mathcad user since version 13, I understand the unexpected nature of this change. Mathcad Prime 6.0 contained both a new PTC-controlled symbolic engine as well as the third-party engine. The versions of Mathcad before Prime (13, 14, and 15) as well as Prime 1.0 through 5.0 used a third-party proprietary engine for symbolic calculation. After December 31, 2021, the only version of PTC Mathcad available to new customers will be Mathcad Prime 7.
