Hi Luc,
The license transfer form does not seem to be working. I have several Mathcad 14 licenses and have tried to transfer some of them to a new machine. The form says I will be emailed a license file within two hours for each license, but I have received nothing yet. I have used this process successfully at least twice in the past two years, most recently in November 2024, but I am getting nowhere now.
Do you have any suggestions what to try next?
Regards,
Philip
Contact PTC licensing (that's NOT this forum, which is for users of the software).
