I bought single user license for Mathcad from Mathsoft Inc, over 20 years ago, When I bought a new PC about 10 years ago, I reinstalled Mathcad on my PC from a PTC CD. Recently I bought a new PC and tried to reinstall Mathcad but couldn’t get a license to finish the install. The software returned an error indicating my laptop isn’t communicating with the PTC account. When I checked my account, I found out it’s a basic one and I don’t have permissions and need to upgrade it. In order to upgrade my account I need a Customer Number and a Sales Order.
Since I purchased Mathcad from Mathsoft Inc, years ago I didn’t get any Sales Order nor did I get a receipt. I only got Mathcad floppy disks to install. When I got a new PC, I don’t recall exactly the process to install Mathcad however I have a PTC CD and installed Mathcad without problems. I don’t recall a need to get a Customer Number and any Sales Order.
Before I can reinstall Mathcad, I need someone in Account Services to get me a Customer Number. Also I need someone who can generate a grandfathered or dummy Sales Order. Then I can upgrade my PTC account and finally get connected and finish installation of Mathcad.
