I just downloaded and installed from Microsoft the scenery add on "EAA Air Venture Oshkosh". Install went OK...scenery and textures added to ADD ON SCENERY file but I could not see the new scenery with either the create a flight or with the included adventures. Can anyone help? Thanks.

Load up a flight in Flight Simulator. Click World | Scenery Library... then hit the 'Add area' tab. Navigate to the SCENERY folder INSIDE the Oskhosh folder. Click OK et voila!

Thanks Rob...worked like a charm.
