You need to remove it fro the registry. There are two places in the registry
where the details of an addin are held, these are the keys on my machine
with Excel 2000, later versions might be a higher version number
Unloaded addins, that is addins that are in the list but not installed
HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Ex cel\Add-in Manager

Loaded addins,
HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Ex cel\Options


If you have uninstalled the addin from code, you should just need to delete
the item in Add-in Manager, whereas if it is still loaded you need to find a
key OPENn where n is null,1,2,3,... for that addin, and delete it.

Note that Excel updates the registry for addins on close, so I don't think
that you can't uninstall an addin via code and think you will see in in
Add-in Manager, it will still be in Options.
