For the benefit of others, I found my solution by using x-setup-pro. It can
be found at
http://www.x-setup.net/home.asp?lang=EN, and is freeware for the
home user (which is where I was encountering my problem). Incidentally, I
had two bad entries. One was for Microsoft Encarta 2000, and the other was
for a Microsoft Encarta utility. Not too surprising there... Encarta was a
pretty poor program.
I lost track of who wrote the following text, but it explains how to figure
out where the problem lies.
"First I went to the registry but there is a lot of stuff there I don't
understand, so I left it alone. Then I remembered X-Setup
(
http://www.x-setup.net/) - this is the best program ever made for Windows.
It lets you tweak all kinds of things - including the Add/Remove programs
list.
"So, open Add/Remove Programs, and open X-Setup. My version may be old and I
honestly don't know if I have a trial, freeware, shareware or hacked version
(but its probably worth buying), so you might have to adjust the
instructions to fit yours. X-Setup uses a folder/tree structure, so dig down
All X-Setup Pro Plug-ins->System->Software Installation->Add or Remove
Programs List Editor. On the right-hand side it will give you a list in
alphabetical order of what should be in your Add/Remove programs (so make
sure you sort that by Name).
"Now in Add/Remove programs find what items are before and after the strange
black/striped/graphical area. Then find those same two items in X-Setup. Is
there something listed between them?? In my case there was - the Electronic
Arts EACom Updater.
"If you get the same, or something else you don't need then you can
uninstall it manually: Select the item, then click "Edit CMD.." Don't
actually edit the command, just copy it (Ctrl-C). Then open a command window
(Start->Run->cmd.exe) and paste (usually just right-click with the mouse)
the command. Hit enter and it should uninstall whatever was causing the
problem."
