Question
Installing mathcad 14.0 upgrade version
When installing 14.0 I get a message saying this is an upgrade and to enter the old serial number. I had 7.0 and the s/n was PU02802D00549 which it does not accept. I still have the 7.0 CD, I put it in the DVD drive and provided the path but it can't read it. I had this same problem in 2017 and it was a ridiculous pain in the butt then, I shouldn't still be going through this aggravation. Fix it already sheesh.
