Home and Office: Installing offline help in LibreOffice.
LibreOffice help may be viewed online; there are also several booklets in PDF available
for download. And there is the "LibreOffice Help" item in the GUI's "Help" menu (shortcut key: F1), which gives offline access to the help documents.
If you try this after LibreOffice installation, you get an error message; this is simply due to the fact that help is not included in the application
file, in my case, "LibreOffice_6.0.4_Win_x64.msi", but must be downloaded and installed separately. When downloading this help file, keep in mind
that it has to be the one corresponding to the application you are actually using: same platform, same version number and correct language; in my
case the help pack file is called "LibreOffice_6.0.4_Win_x64_helppack_en-US.msi".
When the help pack has been installed, F1 should work, but not always does! The problem is that the LibreOffice GUI language and the language of the
help content must be exactly the same. The LibreOffice setup program sets the GUI language to the system default, i.e. the language of your Windows
operating system. If this is for example English (UK) and you install the help file mentionned above, you will get the message "The
LibreOffice built-in help is not installed on your computer."
To resolve this issue, choose Tools > Options > Language settings > Languages and and set Language of > User interface to exactly the same language as the one of your help pack, English (USA) in my case.
On some Internet sites, describing this issue, you may read that you have to also change Language of > Local setting. This seems NOT to be necessary! In my case using the en-US help pack, setting the GUI language to English (USA) and letting the local setting = "Default - Luxembourgish" works without any problem. Be aware that changing the local to English (USA) would result in changing the date, time and number formats!
