A cross-version approach consists of two files. First is a Classic Excel
(i.e., 2000 through 2003) add-in, which does all the work, and detects the
version of Excel. If the version of Excel is Classic, it builds the menus
and commandbars as before. If the version is Excel 12, it opens the second
file. The second file is an Excel 2007 add-in (not installed as an add-in by
the way) with the XML code for the RibbonX modifications as well as the code
that catches ribbon clicks and runs the appropriate command in the Classic
add-in.

But am I right to assume that RibbonX does not work under older
versions? Is there any cross-version system that works well?
