How to remove (Delete) a Word global template add-in from the Add-ins list?

[Tom.Stein]

Okay, propably too late for you, but this helped me and might help others:

The steps above moved the add-in from the 'Active Application Add-ins' list to the 'Inactive' list. It still appears in the 'Global templates and add-ins' list preceded by an unchecked checkbox.

I tried running code twice, no difference. Ideally, I'd like the add-in to vanish from all lists.

You can ".Installed=False" the AddIn, you can ".Delete" the AddIn (as you mentioned) and - tadaaa! - you can delete the file using "Kill(oAddin.Name)". That will physically remove it for the entire outside world. BUT you will still see it in the AddIns-list until you close Word, and you can not use FileCopy or anything to recreate it, as Word thinks this AddIn is still there until you close Word.
