"Type mismatch" exception in Excel.Application.Version

Does anyone know why this exception can be happening?

Hi Andrei,

Can you say a bit more about the context - is this from inside the Excel-DNA code or your own add-in?

Are you making the call through the interop assembly?

Are you able to make the call late-bound instead, as a test?

The result of Application.Version is a string - is that what you're expecting?
