I successfully resolved the problem and now have installed the Windows 8.1 update. It turns out that my Windows Updater didn't install any optional updates. I found two of those, installed them, and that eliminated the Win 8.1 update problem!

Has anybody tried looking at their logs to see which "file is in the wrong format"?

The "Windows Update troubleshooter" does detect two problems and claims it is able to resolve them (this seems to be similar to running the sfc /scannow script). However, I still get the same error code (0x80240031), and the Windows 8.1 updater does not skip those "annoying 50%".
Any other suggestions?
Best regards,
Michael
