Can't modify 67 protected registry keys installing Office 365
In installing and re-installing Office 365 Home 64-bit (on Win 7 Pro 64-bit), and in each set of updates, I get 67± Warnings in Event Viewer about registry keys that are protected and cannot be changed. So far, I have been completely unable to fix this problem.
Any ideas?
FYI - I have posted a lot of detail

Update - So 41± "protected" registry keys have been showing up in Event Viewer Warnings when I run any update of Word or Excel (from this second O365 Home installation).
NOW, in regedit, I have given "Full Control" permission to Administrators in each of these 41± keys. (I run regedit and regscanner64 as TrustedInstaller. So I don't have to change Ownership to change Permissions. Goes much faster.)
Result - in yesterday's normal "Update Now" of Word, which ran some updates, I did NOT get the 41± Warnings. Progress ?? Risks ??
I might go back to my earlier lists of "protected" keys (which were more than 41), do the same, and then run a "Repair" of O365. (Or a total UNinstall and REinstall.) What do you think? Will a Repair or UN+REinstall create different keys and so progress will be lost?
