Try exiting Excel and comming back in. If that does not work try
uninstalling it through the Excel Options screen and then reinstalling it.
It should appear on the far right of the Data tab.

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?
