Unable to link to Calibre after reinstall

I’ve had to reinstall Mac OS and I can’t get Calibre to work now. I just get a no linkable item warning. Calibre doesn’t appear in the list in Automation preferences. Any suggestions please?

Have you tried the usual tips: No Linkable Item in … – Hook ?

Yes, sorry, I should have said what I’d done. I reset the accessibility for Hook, but Calibre is not appearing in the list of apps in automation. Is there a way of forcing it to appear there?

I have still never been able to re-enable Hooking to Calibre. I’ve been through all the suggestions again, but I still don’t have Calibre appearing in the list of apps in automation. Any ideas? Reinstall Calibre?
