Thanks for the reply
No idea, the ticket came back from the developers with "please assist user
by changing the registry to allow an addin to load before all other addins".
I replied with asking which registry key and got an Out of Office, so was a
bit stuck.
Turned out it is HKEY Current
Users>Software>Microsoft>Office>10>Excel>Options> and apparently from there
it gives all the addins and the order in which they load and I can change the
order. Will find out on Monday if it worked. It's new one on me.
