How do you install it manually?
I haven't said to install it manually, you only need to add it manually to the Scenery Library. This, assuming that our installer haven't said anything about errors in the scenery.cfg.
Just to be sure, because this is an easy mistake to make: the scenery.cfg that you sent me and that looked correct, is NOT taken from the FSX folder, right ?
Because in FSX (opposite to FS9) the scenery.cfg that is actually in used is not in the FSX root folder. Instead, is located at:
%ALLUSERSPROFILE%\Microsoft\FSX\Scenery.cfg
You should have sent me THIS file to check for errors. If you sent me the one in the main FSX folder, it doesn't do anything, is only used as a backup to repair the installation so, it's the same as when you install FSX fresh.
