spell check not working for version 5.0.4.2

Spell check quit working when I upgraded to version 5.0.4.2 There are lots of discussion of similar problems on the internet but none that seem to apply to windows 10…that I could find…

Spell check has been unreliable, broken, in 4 and 5
and ignored by the erudite experts at The Document Foundation.

Rename the profile in AppData is no help.
multiple re-installs with ‘Typical’ and ‘Custom’ finds no working Spell check ‘out of the box’

Windows 7 Pro 64 bit and 5.0.5.2 English UK

It’s rumoured that 3.x was the last version where spell check was reliable out of the box.

No 3.x .msi download seems to be available.

Lots of questions - many closed - with ‘Answers’ that don’t help.
Where is there any version of Libre Office .msi for a clean English UK install, that spell checks ‘out of the box’ ?
Please
