How can I get MathCad to update my MathCad 14 license?

 

I installed a new internal hard disk drive.  It has a different MAC Address.  Consequently MathCad will not open and run.

 

I need a set of  step by step instructions to get and install a new MathCad 14 License.

You have a harddisk drive with a MAC address? The MAC address is usually tied to a network interface (LAN or Wi-Fi)...

Any way, you need to read here: https://community.ptc.com/t5/Mathcad-Installation/Assignment-of-Mathcad-14-License/m-p/1047384#M5117
