Need uncorrupted copy of CD English for Mathcad 14.0 M020

You request is placed on a forum for users of Mathcad and Prime. I you want something from PTC you will have to contact their support. But I doubt they will fulfil your request, considering:

https://community.ptc.com/t5/Mathcad-Tips/Official-PTC-Mathcad-15-and-Prime-1-6-End-of-Sale-Announcement/ta-p/818870 

Even if you had an uncorrupted Mathcad 14 CD, you will probably not be able to get it installed AND licensed.

(As you already found out: https://community.ptc.com/t5/Mathcad-Installation/reinstall-Mathcad-14/m-p/924354#M3566 )

Success!
