If you are not doing anything and you get the message, then you will have to
debug your environment to figure out what is causing the message. The
situation you describe is not what is normally experienced, so it is
something specific to your environment.

I do not understand. My add-in does not call Solver on startup. It
merely contains a reference to Solver. I am not unloading or reloading
anything - just booting up Excel.

Any other suggestions? (Thanks!)

Depends on what is causing it. If you are unloading solver, then the
solution would be to check if it is loaded first, then don't unload and
reload it.
