Some belated feedback is better than none.
I've been using it since the last time I wrote about it, manually updating some files like trid defs, unrar, 7z.dll etc and it seems to be working more than fine. Sadly, what seemed to be a very nice New Year's present for 2016, is more than likely not in active development any more.
Kudos to Acheron for posting the link with the different mods so we can hope there will be at least one maintained version left at the end of this very long journey of this piece of software.
Cheers and regards
