Which version of Office? It's not available in Office 2003. In prior
versions, it may or may not have been installed. It would be under the Tools
in a custom install. Look in your Start menu under Start|Programs|Microsoft
Office Tools or Start|Programs|Microsoft Office|Microsoft Office Tools to
see if it has been installed. If it hasn't, go to Control Panel, Add/Remove
Programs, click on Microsoft Office and click the Change or Modify button.
You will need the install source available to do this. Make the desired
selections and setup will install the item(s) for you.
