I'm putting this here FTR as I'm too knackered to follow up right now.

After a bit more digging I ended up with this.

C:\Users\Mark\Documents\MyPython>pip install --trusted-host

   Exception:

       raise BadZipFile("File is not a zip file")
   zipfile.BadZipFile: File is not a zip file

The same file installed perfectly when downloaded and installed in two 
steps.  Whether this is simply a known bug with zipfile handling, pip 
itself, a combination of both or what I've no idea.

I find it slightly irritating that a tool recommended by the Python 
Packaging Authority behaves in such a way, but then I didn't have to dip 
into my pocket to pay for it and certainly won't lose any sleep over it 
as there's such a simple work around.
