Solved, but what a fiddle.
Posters on here gave me a clue with File and Open.

When I click on the link with IE I get the error message and 'Request not allowed'.
But then if I go up and click on File
and 'Open in immersive browser'

Up comes the graph in Adobe Acrobat.

So it does not seem to be the usual direct link for some users.

Yes. If I click on "File ... Open" in IE and then copy the URL into the box, it opens in Adobe Acrobat. Clicking directly on the link does not work.
