Okay, so I took a much closer at my installation, and I feel like a dufus. I had created a custom setup file for my installation of Office 2000, and I apparently did not set it up correctly to install the VBA help files. When I went to Control Panel > Add or Remove Programs > Microsoft Office 2000 SR-1 Professional > Change > Add or Remove Features, I discovered I needed to include the VBA Help Files among many other things that did not get installed.
After testing it, the help files work fine.
Thank you!
