Convert MCD to MCDX

You can convert old Mathcad files (.mcd) to the newer Mathcad Prime 2.0 MCDX format only with the proper version of MathCAD, no 3rd party software will help you here. Just keep in mind that when you convert a legacy file to Mathcad Prime 2.0 format, the converter annotates all unsupported content and saves the original content as an image. Annotations are also used to flag differences in calculation methods, result formatting, or operator display.
