Office 16 Click-to-Run Extensibility Component could not modify 137 protected registry keys during installation or update of Office 365

In installing and re-installing Office 365 Home (64-bit install on Win 7 Pro 64-bit), I get approx. 137 Warnings in Event Viewer like the following:

Product: Office 16 Click-to-Run Extensibility Component. The application tried to modify a protected Windows registry key \msinkdiv.InkDivider.1.

I did a deep uninstall and reinstall just to see if this could be avoided, but no.  It happens on each install or repair or reinstall.

Here's all the info for one of these - but keep in mind there are 137 different ones (different keys being named):
