i wanted to install Mathcad 15

Installation should be no problem....IF....you have an installation source.

Getting it licensed is the challenge. Do you have a license?

I think you should first read this (and note how long ago this is):https://community.ptc.com/t5/Mathcad-Tips/Official-PTC-Mathcad-15-and-Prime-1-6-End-of-Sale-Announcement/ta-p/818870

You cannot. You should read this: :https://community.ptc.com/t5/Mathcad-Tips/Official-PTC-Mathcad-15-and-Prime-1-6-End-of-Sale-Announcement/ta-p/818870 
You can only get a license (subscription) for Mathcad Prime 11, Prime 12 is scheduled for later this year. If you insist on version 15, then you have to wait about 3 years, when Prime 15 comes out...

Sorry to annoy you, but the reason why I insisted on version 15 is because I had xmdc file which I wanted to open. So I managed to convert it to mcdx file. Everything is okay now
