I have developed an add-in using Excel 2002. Some of our customers are using
older versions of Excel. Could anyone point me to references that might
explain different deployment options? For example, should I ship both an
Excel/97 and an Excel/2002 version of my add-in? By only using Excel/2002
can I make both versions? Where is the best place to install an Excel
add-in? Any guidance appreciated.

Regards,
Steve
