Maybe you could just have MSIE open the excel file directly in excel.

Hi all.
I'm trying to open an excel sheet in IE. it opens but the
edit,view,favorites tabs are greyed out. Only file opens up. User has rights,
as we tested this on another machine and it works there. Using the latest IE
and updating office to the latest service packs. This machine has adobe
acrobat full 6.0 and the others dont. if that makes any diffrence.
