I have in my company installed Excel 2003 and Excel 2007.
Excel 2003 is here because some addins not suport newer version.
How to, when I click to .XLS file automaticaly start Excel 2003, NOT 2007?

I try with Control Panel... Folder Options... File Types but allways after
double click, XLA file was started in Excel 2007.
Maybe some change in RegEdit?
Thanks.
