I've just installed GIMP 2.8.6 and the English (United Kingdom) user
on Windows Vista.
Initially, the local help was not working, and Edit > Preferences > Help
System indicated "The user manual is not installed locally". After a bit
of searching, I tried renaming the folder:
C:\Program Files\GIMP 2\share\gimp\2.0\help\en_GB\
C:\Program Files\GIMP 2\share\gimp\2.0\help\en\
and the local user manual started working as expected.
It appears the UK English help installs to a folder (en_GB) not
recognised by GIMP. Not sure if this affects other operating systems as
well, or just Windows.
I was about to file a bug report as I couldn't see one already, but
bugzilla.gnome.org seems to have stopped responding. Will try again
later, but anyway thought others might like to know the workaround.
