If your license is working on one laptop the license is locked to the MAC address of that laptop.
The license only works on one machine at a time.
License needs to be transferred from the laptop it works on to the second one.
To transfer a PTC license for Mathcad Prime or other software, log in to your account on the PTC support website and go to the "manage license" section. From there, you can perform an advanced search, find the license you want to move using the old machine's Host ID, and use the "move license" option to specify the new machine's details. The new license file will be emailed to you for download and installation.
