OK, thanks for the quick reply..I will check out the VHHH in the .cfg file, but it does not seem to cause any trouble with the ORD install
If you haven't Uninstalled 1.0 before 1.1, the scenery.cfg update step is not necessary, because the area for O'Hare was already there from 1.0. But, in case you need to Uninstall, since the Uninstaller removes the O'Hare area, if you don't fix the problem, a subsequent reinstallation would not be able to add O'hare, and the scenery will not appear, unless you manually add the area, of course.
I suggest fixing the scenery.cfg anyway, because other installers might be fooled by it.
