Hi Jim

There's an outstanding issue with functions not being unregistered
when the addin is unloaded, as mentioned in a previous thread Excel's
xlfUnregister function is broken.  I'm aware of a workaround which
involves re-registering a dummy hidden function and that might be a
solution.

But I'm not sure that's the issue you're referring to -
- If you stop and restart Excel, does that resolve the problem?
- Are you trying to keep two different versions of QuantLibAddin
available concurrently on one machine?  Or are you talking about a
permanent one-off upgrade from an older version to a newer one?
- Are you loading the XLL via the addin manager or with File/Open?

If you could send me instructions for recreating the problem I'll try
to provide a fix.

Regards,
Eric
