Office 2003 Excel Add-ins during silent install?

We are currently using the Custom Installation Wizard to create a transform file with all of our Office settings. Unfortunately I am unable to find anywhere where I can tell Excel to install all of the optional Add-ins during our silent installation. Currently we are installing these manually after installing Office by going into Excel and checking the "Analysis Toolpak", "Solver Add-in", etc.

I'd like a way to enable these add-ins automatically during my silent Office 2003 setup. We are installing Office in the following way using our transform file created using the 2003 Custom Installation Wizard:

"setuppro.exe" "TRANSFORMS=%INSTALLERDIR%\CTS-Office-2003SP2-FAC.MST" REBOOT=REALLYSUPPRESS /L*V %temp%\Off2003.log /qb-

At one point we had tried using regshot to see what registry keys were changed when we enabled one of the add-ins. All this got us was for the check box to be checked in the Excel Add-in menu, but the add-in wasn't actually enabled in Excel (ie: it didn't show up under the "Tools - Solver" menu).

Has anyone had any luck figuring out how to do this? Any help would be greatly appreciated!
