Cannot activate mathcad prime 3.1 using licence files I am a long time mathcad user. After retirement in 2016, I purchased a permanent licence for mathcad prime 3.1. It was working fine until recently, when the installation reverted to express mode.
my attempts to “re-activate” the installation to to full functionality have been unsuccessful.
I have obtained licence files through the self-serve tools, but when I try to use them, I get a message stating that the server is unavailable or down. Because I do not have an active support account, the PTC support team is inaccessible to me.
I find this to be maddening, because I have a permanent licence for Mathcad, I cannot get it to work, and I can’t find any help at PTC.
any suggestions or assistance would be appreciated
