MathCAD 15 Installation executable unobtainable through ptc.com

[KO_8559826]

Need assistance obtaining installation executable for MathCAD 15. Licence purchased in 2018 and used through 2021 (still have licence file, so that's okay). Need to install MathCAD 15 on new machine for compatibility with older MathCAD software.

That's unfornunate. What is the recommended solution to resolve
compatibility with older MathCAD files?

[VladimirN · Accepted solution]

Starting from the 7th version of Mathcad Prime, you can use the built-in converter.
