I ran the two parts of the instructions under 5 above. I had to clear space on my 500GB drive C: which was nearly full. As well as backups and moving big files to D: I did a disk cleanup. I notice that this included cleaning up Windows Update files. I trust that this has not affected our progress to date.
Here is the edited cmd prompt:
