Office Click-to-Run Extensibility Component can't modify registry keys

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):

SO - What do you think?

Ranger - thanks for interesting links.

However, FYI, I have installed O365 only on my Win 7 Pro 64-bit, not my Win 10 Pro 64-bit.

Your links are interesting, esp. the lennytech, but I have NOT had the worse app-crash issues described in Lenny's artcle. As far as I can tell, my Office 365 Home (which gave me Office 16) is working. But I certainly don't like the numerous Warnings in Event Viewer I describe above.

What's interesting about the lennytech is that when I first installed the O365 with the help of the MS call-in team, the MS tech installed the 32-bit version of O365. I asked him to uninstall and re-install the 64-bit version, and he did. Maybe that first install set up those registry keys and locked them somehow. They have apparently remained locked even though I ran the DEEP O365 uninstall twice.

Not yet ready to try the regedit and uninstall surgery described at lennytech. But it might be an experiment next weekend if no luck elsewhere.

More info:

I went to one of the registry keys in the Warnings and found that its Permissions are Read Only and its Owner is TrustedInstaller.

There are way too many of these keys for me to try to change Owner and Permissions (and then change Owner back).

Is there a generic script for taking a list of keys, changing their owners and permissions, then changing their owners back?

What is MS doing if its own installation program doesn't deal with this?

To all - my many weekend days with MS O365 Help has gotten nowhere. With the help of a MS tech2 in India, an unbelievably thorough UNinstall and REinstall of O365 home still generated my 70± Warnings that something "tried to modify protected registry keys", many of which are about msinkdiv.InkDivider.


The tech2 insisted this is normal. What total garbage.



Has anyone else ever had this?

FYI - This is still a problem three years later, after many updates to my O365 Home 64-bit and my Win 7 Pro 64-bit. The only difference is that there are "only" 21 Warnings on each update of O365 Home 64-bit.


Anything new out there?
