Frequently asked questions

Why does MedCalc give an error message 'This is not a MedCalc data file' when reading some MC1 files?

This occurs when you are trying to read a data file that was created by a more recent version of the software.

You should update your copy of MedCalc. Updates are free and are available from the download section of this website.
