So I followed your link, hunted around how to make a backup. thought I found the answer tried:
C:\Users\JAY>%APPDATA%\libreoffice\7\user
The system cannot find the path specified.
I think help is meant for developers/programmers, not mere mortals.
Ready to give up. Maybe uninstall and reinstall Libre Office?
Why are you complicating things???
There is special formatting to show what is to be copied and pasted. There is even a step by step instruction saying how to access it. There is NO need of any terminal at all. Just follow the instructions. See especially this section.
Reinstalling will hardly change anything if the problem lies with the profile.
With all due respect, to you it may seem I may be complicating something simple. Not to me.
after much effort I was able to find in Explorer: C:\Users\JAY\AppData\Roaming\LibreOffice\4\user
However, there is no folder called profile that I thought I need to copy (or is it the final ‘user’ I need to rename?
Then it looks like there a folder called ‘wordbook’ which contains a DIC file called standard.dic which was last modified on 3/15 and is (only) 1KB
Is this relevant?
The relevant point is that you have to RENAME the folder user as stated in the various tutorials and relaunch LO to see if it’s OK or not. It has never been said that the profile was a folder called profile because it is actually called user. That’s the point of the whole tutorial.
I’m still not confident that I have the technical background to follow your tutorials, but I have started over.
I would ask your patience – I have devoted many hours to this.
In your tutorial [Troubleshooting] Spell check in OpenOffice (View topic) • Apache OpenOffice Community Forum I cannot get past Step two.
Attached is a file with all the screen shots.Spell Checker.docx
OK started over again.
Tutorial per your suggestion
Below are the steps *(with my results)*Check spelling as you type must be checked
*Was not checked So I checked it (corrects typos in real time)
In the Language drop-down box, select Your_language, which must be preceded by the checkmark (✓) icon.
Does not have checkmark
If you don’t see it, then the dictionary is not installed or not recognized by LibreOffice. Try to install it again. Just click the link Get more dictionaries online…
Followed link to Extensions and only could find “US english Spellchecker” (poorly rated) There is no indication how to download or install dictionary, either in the tutorial or on the linked page.
In the Spelling module, a dictionary must be checked (by default Hunspell SpellChecker).
Not Checked
In the section Default language for Documents, Western field, select Your_language in the drop-down list.
Checkmark icon not visible
Next steps please??
no indication how to download or install dictionary
Because it is just an extension. Thus, simply click on the green DOWNLOAD button and install it by the conventional procedure.
Note that you can also find spell checkers at the LO extensions site.
Anyone out there? I don’t want to jump ship back to Word 
You have been given with all relevant guidance. As per your description, there is no spellcheck dictionary. Find and install.
I have followed the tutorial and per my comment, I hit a dead-end. I would appreciate some specific guidance as to next step(s).
I am not a programmer or developer. I realize folks are here as volunteers. I appreciate that. In other contexts where I have expertise I contribute my time as well.
See above. The specific guidance is (once again): install a dictionary.
One more thing to try: LanguageTool. Install, go to Tools → Language Tools → Options. On the General tab, tick Add LanguageTool to LibreOffice spell check.
More hours of frustration. None of the extension options suggested worked.
Re LanguageTool, your direction go to Tools → Language Tools → Options. was not an option
Tried Tools → Language → More Dictionaries online. Downloaded first Option (English Dictionaries). Installed (said it would replace older version) and I tried and got a warning “Cannot Detect Media type” clicked OK. It asked me to restart LO which I did. Still no Spell Checking
Oops, my mistake, it should be LanguageTool, not Language Tools (if LanguageTool is installed, both menu items will be present). But did you actually install LanguageTool?
Not sure, since I got that error ‘warning’. How would I check?
You did not mention any warning. Never mind, go to the extension manager and see.
https://help.libreoffice.org/7.0/en-US/text/shared/01/packagemanager.html
" Installed (said it would replace older version) and I tried and got a warning “Cannot Detect Media type” clicked OK. It asked me to restart LO which I did. Still no Spell Checking" (above)
Provide more detail. How did you get to installing the extension.
I’ve tried so many routes I’ve forgotten details (though always got the same message). I’ll try later again and document.
