CommandBar menu handlers in VSTO Addin( created in Excel 2010) are not handled in Excel 2013 once a workbook is opened. RRS feed

  • Question

  • Our Application launches Excel and loads a VSTO Addin via COM.  The Addin creates menu items using CommandBar control.

    During running of the application, the menu commands in the addin work as long as there is no workbook open.  They stop working once a workbook is opened.  This works fine in previous versions of Excel. 

    How do I fix this?
