The Helppack does not work

I installed “LibreOffice_25.2.5_Win_x86-64” in French
Than I installed “LibreOffice_25.2.5_Win_x86-64_helppack_fr”
When I use any of LibreOffice section, F1 or “Aide de LibreOffice” (help of LibreOfice) does not work at all… Nothing happens when I click on “Aide de LibreOffice” or use F1
So, the helppack does’nt work.
In the past I had no problem with this ; but since at least 2 or 3 updating of LibreOffice, the help does not work
I don’t understand why this does’nt work anymore…

make sure the language interface is fr,
and check if your browser can access local files.

Help Files not recognized after Installation
Browser can't find local help files

The link with helppack did work during years and I changed nothing on my side
Obviously, recent updates of LibreOffice and/or LibreOffice Helppack have distroy or forgotten a link between the 2 programmes.
