Many thanks for the reply Jim.

I'm still baffled as to why this would be happening, I'll take a look
registry.

When a non-built-in addin is selected in the Addins dialog it is recorded in
the registry under

HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\E xcel\Options

replacing the "11.0" with your Excel version. The specific item will be
OPEN or OPEN1, etc., depending on how many such addins you have. The only
way an addin selected for loading in Excel would not be selected
subsequently is if something altered the registry or the user logged in
under a different user name, as far as I know.
