AutoUpdate fails trying to update old V3.11 of AutoUpdate on MacOS Sequoia 15.8.1
I have the latest version of AutoUpdate (4.85) installed on my Mac. For several years and versions of MacOS, every time AutoUpdate runs it fails to update AutoUpdate Version 3.11 with a "Check Error..." or Download error.
I've searched for solutions but only find how to totally disable AutoUpdate. I want to remove whatever remnants of V3.11 are somewhere on my system so I can run the latest AutoUpdate without this failure. Any suggested fixes...?
TIA

It is is caused by leftover components from the legacy Microsoft AutoUpdate v3.11 still present on your Mac. May try to fix by manually removing those remnants (launch agents, helper tools, caches, and preference files) so that only the current AutoUpdate v4.85 remains.

I've looked in all those folders and nothing stands out to me to belong to the old v3.11 version. And the only file in Library/Application Support/Microsoft/ is v4.85 of the Microsoft AutoUpdate.app
