Thanks guys. You've got to stay awake, eh? I read an out of date post somewhere and thought that was the state of play today.
So still got a problem though.
I went and got 7.1.0 and tried to install it and got an error "does not contain a top_level_init_py" or something similar. Attached screenshot.
hmm. in preview that didn't work.
I'll try linking to it:

Belay that. I misunderstand and unzipped nothing. I just now tried unzipping the first 'outer' zip file and installing the 'inner' zip file. It worked fine.
Sorry for the needless enquiry.
