I gave that a try, but the problem remains and I’m still getting a 0x80070bc2 error for the 2018-03 Cumulative Update and 0x80070643 for 2018-01 and 2017-12.
There were two items on the Installed Updates that could not be deleted or selected… “Update for Microsoft Windows (KB4054022)” on 1/5/2018, and "Security Update for Microsoft Windows (KB4048955) on 11/15/2017
I’m considering trying a Recovery Reset and starting again with a fresh slate. Is there anything that I need to know before attempting that with the Eve V? Any specific software, like the screen calibration, that I need to worry about?
