Migrate Prime 4 and MathCAD 15 to new computer
I purchased the educational MathCAD Prime 4.0 with MathCAD 15 in 2017. The software combination is currently accessible and usable from my old computer which has some case deterioration issues. I have purchased a new computer and wish to use the software combination from this new computer.
After installing the software on my new computer, I followed the process on the inside of the CD case to acquire the new license and was met with the message that the Program ID already expired. I followed the link which brought me to this page.
I have MathCAD 15 files from versions 2-15 arising from an academic career and would like access to them, and, certainly, I'd like to migrate many into the Prime environment. The combination of Prime 4.0 and MathCAD 15 both resident on my hard drive is necessary to enable this migration.
I read from the PTC Community that PTC's product manager has committed to honor all existing licenses - that which came with my purchase is a perpetual license. I believe that PTC has the capacity to resolve this issue with my license.
