This is for Excel 2016.
I did find this amongst a hundred other web results regarding the removal of COM add-ins, which I figured for myself, there's a handy remove button right in the menu:
However, there is no such button for the "Excel Add-ins" menu, the button for which is adjacent to the COM Add-ins button:
I can deselect it of course but that doesn't remove it from the list, even after restarting Excel.
So, how do I get rid of them?
if it helps, these were/are .xla
add-in files on a shared drive, so I can't just delete them.
