As shown above, I am trying to roll back my current version of Microsoft Office to an earlier version.
This process is discussed here: https://www.slipstick.com/outlook/20...013-click-run/
and documented here: https://support.microsoft.com/en-ca/...6-click-to-run

But this error about needing a system admin is confusing me. I am the system admin for my computer, but I need to know which setting to change, or what to modify to get this error out of my way.
