Installed unoconv and libre office as in https://docs.moodle.org/35/en/Universal_Office_Converter_(unoconv).
When trying to annotate a .docx, unoconv convert the file to an only blank page.
The generated file is not saved in the assigment; looks like unoconv do no convert anything.
added this first line to the batch file calling unoconv:
echo %* > C:\Unoconv\Unoconv.log
@"C:\Program Files\LibreOffice\program\python.exe" c:\unoconv\unoconv.py -v %* >> C:\Unoconv\Unoconv.log
The %* reports as "--version" in my log file.
I think there's a problem in the invocation of the batch file; maybe wrong/missing parameters.
Any help would be appreciated in this kind of reverse engineering.
