Will return to Calibre 7.26 now, but would very much like to be able to update. Thank you for any time you can invest in looking at this issue.

Given that your Windows 10 is seriously out-of-date, I suggest you upgrade to the latest Windows 10 and then try calibre 8.0.1 again. There have been instances where QT does not work on such an old version of Windows 10.
