The ms web browser is part of IE. Once again, it shouldn't be
part of your install package. I don't know why it isn't smart
enough to know that, but I would try to take it out. I expect the
diwhois.dll doesn't have any dependencies so you can probably
ignore the warning for it.
[edit]When I say take it out, I mean from the install package, not
the project. Obviously, you need it in the project but it should
depend on the IE components already installed on the target
computer.[/edit]
