When I open an Excel file by double clicking the file directly (with the Excel 2010 application closed), Excel 2010 opens the file but does not load any third-party add-ins. I checked the COM add-ins and the add-ins are checked, but, they are not showing
up on the Ribbon.
However, if I open up the Excel application first (with a default workbook), the add-ins load normally. Further, the add-ins remain loaded if I then open a file (the same file that I previously tried to directly open) from the Excel Open Dialog box. However,
even if the application is running with the add-ins displayed in the Ribbon, should I double click a file directly, it will open in a new instance where the add-ins once again are not visible in the Ribbon.
I am at a loss and would appreciate any ideas.
Thanks in advance.
