Remove Add-in in Powerpoint with VBA - vba

Question

I have a VBA Add-in in PowerPoint that is updated occassionally. I wrote a code in VBA where every Monday there is a check wether a newer version of the Add-in exists. And if it does, PowerPoint automatically updates the Add-In. So far, I have this accomplished:
Deactivate the old Add-In in PowerPoint
Delete the old Add-in in Microsoft's Add-In folder
Copy the new Add-In to Microsoft's Add-In folder
Activate the new Add-in in PowerPoint
However, I can't seem to find the right command to delete the old Add-in in PowerPoint. The old Add-in is still in PowerPoint's available Add-ins, and PowerPoint also lists it under the inactive Application Add-ins.
Here's part of the Code that first deactivates the Add-in, and then tries to remove it from PowerPoint.
Dim oAddin As AddIn
For Each oAddin In Application.AddIns
If Left(oAddin.name, 16) = "PPT ACO Add-in V" Then
oAddin.Loaded = msoFalse
Kill (oAddin) '<-- these is the line of Code that doesn't execute
End if
Next oAddin
The program would work, but after some time I'd have a bunch of inactive Add-ins laying around in PowerPoint which will be very confusing to users.
Thank you so much for your help guys.

Answer 1

very late answer, but since I passed by and I spent myself quite sometime on this issue, instead of
kill (oAddin)
you need
kill oAddin.fullname
although you should also remove the addin from the collection of AddIns and maybe unregister.
Also, in version 2010, you might get an error of permission denied when you try to delete the file. This is caused by ppt not releasing in time the open addin file. In fact, a timer does not solve it. But a second kill will actually work.
