Spent over an hour trying to get matplotlib to work

Thanks, both. As I said, the problem each time is the above error message.

Knight18, I think it installed just fine. It certainly had the bars for installation go up to 100% etc. The only thing I would say is different is I typed Windows key CMD to open the command prompt to install. I don't think I did as you suggest and opened it from the same directory as the exe.
