When you use Dennis's tlb in a managed code application a PIA is created for
it (Interop.XLIRibbonExtensibility.dll). If you have projects created using
an older version of VS that used the tlb get the PIA from one of those
projects and add it to your VS2010 project and it should work just fine.

Hi Ken

Thank you for persisting with this for me.

I am not sure what you mean by " I took the XLIRibbonExtensibility PIA
from an existing project to the tlb".

Thanks
Sanjay
