Need help in convert Mathcad file that was created in version 14 to Prime and no longer have Mathcad 14 installed in my computer. Please advice.
As Vladimir already noted you can attach the worksheet (if you are allowed to do so) and someone here sure will find the time to do the conversion for you.
You should state which version of Prime you are using as a file converted to Prime4 format would not be of any help to you if you use Prime 3.1.
To do the conversion yourself you could download and install the trial version of the latest Mathcad 15 and use the converter of Prime to o the job.
