I'm running latest Calibre on Win 10 and for the last few versions I can't get Epub to convert into docx. Convertin Epub into Azw3 works with no problem.

This is how the Conversion Error dialog ends:

Traceback (most recent call last):

If I convert Epbu>Azw3>docx it works with no problem whatsoever. So I'm not sure how to go about this. None of the export settings are customized.
