@burnout426 Just sorted it. Now working and offering a variety of English language dictionaries. I suspect I had an error in the file name (en_gb.zip). My fault. Thanks for your confirmation of method.

@burnout426 Thanks for your help. OK, understand that. The problem is if I download the English Language Dictionary pack from your link it doesn't show up on the list of available dictionaries (on the drop down menu) when you try to make a choice of the preferred language.

@burnout426 said in a problem with downloading and activating another spelling checker in Opera Mail:

Go to https://extensions.openoffice.org/en/project/czech-dictionary-pack-ceske-slovniky-cs-cz and download the extension. You'll get dict-cs-2.0.oxt. Rename it to cs.zip and put it in the "dictionaries" folder in Opera Mail's profile folder. Then, start Opera Mail (or restart Opera Mail) and it should be available for selection and use.

I've the same problem with Opera Mail. I'm trying to install the English - British dictionary and when looking in the Opera Mail profile folder (under my User/Roaming) I find the correct dictionary has downloaded - or at least shows as downloaded but refuses to install and reverts to the default English - US dictionary. I tried another dictionary for another language and the same problem occurs. The dictionaries are downloading as zip files but these then refuse to install. Any ideas?
