English Spellchecker not working, hunspell not listed in options
I read a bunch of discussions and tutorials and none fixed my problem.
English (USA) is the selected language, and everything else under "Options -> language settings" seems to be in order OTHER THAN hunspell is missing under "Options -> language settings -> writing aids".
A search for "hunspell" gives many files in \PortableApps\LibreOfficePortablePrevious\App\libreoffice\share\extensions\dict-en. No actual file names with "hunspell", but "hunspell" is in many files there.
