Mathcad 14: How to Re-license Replaced Hard Drives/ New Replacement Computers

[DW_1261370]

I work my business alone at home. I have a LAN with three computers which I use for backup purposes and Mathcad 14 installed. I'm the only individual operating Mathcad on this LAN. My laptop (one of the 3 computers) recently failed and required a new SSD hard drive. I've installed Mathcad 14 on this laptop but can't use it because of the license issue. I need to update this Laptop with a new license. The other 2 computers are older than 15 years, so they both will see a replacement in the near future. I assume their replacements will also need to be re-licensed. Please help me acquire one license that I can use now for the laptop and also for future replacement of the other 2 computers.

The support for Mathcad 14 ended long ago, read here: https://community.ptc.com/t5/Mathcad-Installation/Mathcad-14-How-to-Re-license-Replaced-Hard-Drives-New/m-p/1039145#M4950 

If you only changed the SSD, the MAC address of the laptop should not have changed, so the same license file should be usable. Of course you have made a backup of that, didn't you?
