I have installed Excel 2007 on my work laptop (Windows XP), but have kept all
Office 2003 products. When I install and activate the add-in for Analysis
Toolpak, it shows as installed in Excel Options -- Add-Ins, but the Data
Analysis group does not display under the Data tab.

I am running Office 2007 on my home PC (Windows Vista) and it all works fine
there. I am confident that I know how to install and activate the add-ins for
Excel 2007. I think the problem is a result of still having the older version
of Excel still installed, which is necessary for work. I need Excel 2007 on
my laptop for a Stats class. The add-in works fine in Excel 2003.

I have found multiple mentions of this problem, but none with a proposed
solution. Example:

Is it possible that the add-in simply won't work with both versions installed?
