We received an email inquiry which I had forwarded to a Mathcad product manager. I thought it may be useful for others, too, so instead of just emailing the response to the customer, I am posting it here as well.
We need to convert .mcd to .mcdx...We have Prime 22.214.171.124 What do we need and how much does the program cost to do this conversion.
The .mcdx file format is Mathcad Prime. The .mcd file format is for earlier versions of the legacy software, later versions of the legacy software use the .xmcd file format.
If this customer uses Mathcad Prime 6.0 there is a converter that comes with the software they can use to convert all .xmcd and most .mcd files to .mcdx - ‘most’ .mcd as we only go back as far as something like legacy Mathcad 7, which was late 90’s I think.
From the Input/Output tab in Mathcad Prime 6.0 they can find an ‘xmcd/mcd converter’ button - clicking that will open the converter. They will need the latest version of Mathcad 15.0 (M050) for that to work, and they can download that currently from the support software download site (Prime 7.0 converter does not need Mathcad 15.0 for the converter to work).
Hope this helps! For additional questions, don't hesitate to open a Support ticket!
