Apparently Dragon did work in Libre 4.4.5.2 .
I want to download it and can’t access it here on the Site. Fails on the actual download file area.
What means “fails”? Which is the page (post link) from where you are trying to download it, what browser do you use, and what exactly is the problem you see.
Use http://downloadarchive.documentfoundation.org/ to actually download any old version released by TDF.
