Somewhere along the way of installing and customizing Delphi 2005 with update 2, various 3rd party packages, and customizations, I lost the ability to view the contents of the Delphi 2005 help file. In order to get this functionality back, I used this fix:

"c:\Program Files\Borland\BDS\3.0\Help\Common\regHelp 7"

After this command executed and the help was rebuilt, everything was fine again.
