When I search for an Excel page using the documents shortcut and click on
the Excel document, the program opens in an Aero looking display, and a box
opens telling me to enter my product key. The title bar of this box says MS
Home and Student 2007.

I do not have 2007, I have 2003.

Then, if I open Excel by going to All Programs and clicking on the MS Excel
link the program opens normally in Excel 2003.

What can be causing this behavior ?
