Here was the problem (and the fix).
Photoshop Elements 4 (and I assume a other Adobe programs) installs Help Center v2.0.
CS2 comes with Help Center 1.0. It will "not install". I tried to force the install manually (from the msi install file) and I finally "saw" the error - that it won't install since a newer version already exists.
The only way I found to uninstall 2.0 help center was to get my elements CD, find the MSI file and right-click - uninstall it. Even uninstalling Elemnets won't get rid of it. I had to manually do it (right click the 2.0 msi file and select uninstall).
Once I did this - sober yet!!! - I was able to reinstall CS2 and the files all installed.
Now I am gonna play with my new toy!
p.s. I tried the FAQ solution and it didn't help.

I installed CS2 over Elements 4.0. When I ran CS2 - everything looks great (much faster than Photoshop Elements).... however, when I select help, the Help Center opens and the only product listed is Elements.
No help for Photoshop CS2 or for Bridge or for ImageReady.
I assume this is a common issue. Any suggestions how to get help back?
