Hi jhandley1967,
If you have a perpetual license for Mathcad 15.0 you can still request to move your license file to a new machine for the purposes of hardware replacement- the link to the end of sale announcement that Vladimir provided above includes an FAQ document link that covers that question, among others related to the end of sale process. Even if you no longer pay support for the perpetual license, the PTC license management webtools can be used, with your original order details, to request to move a license.
If you have any more questions on this, please reach out to me here or via direct message, and I can forward you on to the relevant people to help.
Many thanks,
Andy.
