I have a machine with both Excel XP and Excel 2000
installed. It's a long story but I uninstalled Excel
2000, Installed Excel XP, then needed the excel9.olb to
fix a programming issue so I reinstalled Excel 2000. The
problem I have now is that Excel 2000 loads by default,
whereas I would like to have Excel XP load by default.
I've changed the XLS file associations and that works
fine, but when I run code to launch Excel it is still
launching 2000 instead of Excel XP.

Does anyone know of a registry key, etc that controls
which version of Excel takes priority when more than one
version are installed?

Thank You
