I have installed Office 2003 on my desktop. When I try to "save as" a previous version (Office 2000) of an Excel document, I do not see an Office 2003 Excel listed. When I browse to the Office11 folder and select the Excel 2003 it is still not listed in the "Recommended Programs" list. I installed Office 2003 on a new laptop with no problem. Both computers are running Vista Home Premium.
