I attempted to install Excel 2000XP but the system asked for a later O/S.
My next move was to install Excel 97 Viewer , the choice of which is that
I have found a book :Teach yourself Microsoft Excel in 24 hrs.

The problem now is that despite the viewer is installed I can't get it to open as a Set Up window pops up with 2 buttons : top ..Reinstall [that is greyed out] and bottom : "Remove All" with the words : Remove all previously installed components.
Could someone please advise me on how to open the Viewer. Thanks
