why does command line execution of soffice.exe not work?

I’ve opened a powershell in Windows 7, and want to do some batch processing (html to odt) of some files. When I try to execute soffice (./soffice … or ./soffice.exe … --version), nothing blows up but there is no output. What’s going on?

This is tdf#121498, fixed in 6.3 (scheduled for summer 2019) - I described the fix here. In the meanwhile, you could use cygwin to launch LibreOffice to see the output (and then, don’t forget to convert backslashes \ to forward slashes /). This will enable you to debug what goes wrong with the command you issued.

Thanks. When I use cygwin, I suppose I need to also install Libreoffice? I’m an old Unix/Linux user so this is not a problem.

well - you seem to already have LibreOffice on your system. Just install cygwin, and use it as another shell that allows you to use unix syntax to call Windows stuff, including LibreOffice already present (e.g., issue "C:/Program Files/LibreOffice/program/soffice.exe" --version).
