Thanks

No - direct cable connection between the camera and the PC via a USB cable

Many thanks

The camera is not even visible in Device Manager - the PC just does not seem
to want to connect to it at all. Does that modify your advice?

Did you also install the Canon software?

Many thanks

The camera did come with software, which I have tried un-installing and
re-installing without success. The software does appear to be optional - it
says-so in the manual, and the camera is recognised by a different PC that
doesn't have the software installed. So I am more suspicious of the Windows
drivers (twain.dll / twain_32.dll) than of the Canon software, or perhaps the
Registry settings, but not really sure what to try next

What did canon support say when you told them about the problem? Oh, you
haven't contacted them yet? Hmmm.
