I have a user who is using Excel Services with MOSS who needs to modify a
workbook and save it back to MOSS. The user only has Excel 2000, and Excel
Services requires the workbook to be in Excel 2007 format.

I've installed the compatibility pack and we are able to open the Excel 2007
workbook (opens as a Read-Only file "Xl0000001" workbook). However, when I
try a Save As... there is no Excel 2007 format in the "Save As Type" combo
box.

If I open Word and open Save As..., I see the Word 2007 formats. If I open
Excel (by itself) and open Save As..., I do not see the Excel 2007 formats.

Is there an issue with the compatibility pack?

Carl.
