Hi Nelda
Not quite sure myself but may be that the Excel files you are opening were
created in an earlier or later version of Excel and when you try and open
them they search for that version to open in... maybe.

Would suggest trying to save a new workbook, ensure you select the version
of Excel you have installed when saving and then try to reopen and see if you
still have the same problem.

I have Excel 2002 loaded on my PC. Just recently, when I try to open an
Excel file, it goes thru Windows Installer and comes up with MS Office 2003
setup window.....asking me for user name, initials, product key.
In order to get around this, I have to open my Excel 2002 program first, then
Open my file.

Can anyone please tell me why this is happening all of a sudden? It is very
annoying.

thanks,
