Maybe we need to add something to the existing warning.  It currently 
says, "You can still use setup-<arch>.exe to remove installed packages, 
but there will be nothing to install.  Press OK if that's what you 
wanted or Cancel to choose a different directory."  We could add that 
they risk uninstalling required packages if they proceed.

Of course, the same thing applies even if one or more setup.ini files 
are found but don't include the base packages or the dependencies of 
installed packages.  In this case, however, it means that the user has a 
homemade setup.ini, so we probably have to assume that they know what 
they're doing.
