Hyperlinks to Excel File from Website
 

I am trying to distribute code that adds a menu to a users
Excel application from a web site.

I have tried hyperlinks, but some users open Excel
hyperlinks in a browser and the code fails.

Is there a way to detect if hyperlink (from a web page)
opens Excel in a browser?

Is there a way to force a hyperlink to open in Excel (the
application - not in a browser)?

Is there another solution?

Any suggestions would be appreciated.
