Hi,
it seems to me that several files in this path are not up to date:
https://sourceforge.net/projects/gretl/files/manual/
The thing is that here on Windows the freshly installed snapshot brought
along the right manuals and saved it into C:\Program Files\gretl\doc,
but gretl instead downloads the outdated versions from the server above.
(Apparently having checked that in
C:\Users\<username>\AppData\Roaming\gretl\doc no help files are present,
given that I have deleted the old ones there.)
thanks
sven
