Using Aerosoft's EDDF Frankfurt for P3D, GSX always points to \scenery\APX50140.bgl as the AFCAD. This Aerosoft product for some obtuse reason installs and expects to find the AFCAD in a location other than EDDF\Scenery: \Aerosoft\Afd\scenery. As a result, GSX works but its world is misplaced/skewed from the world shown in P3D making it unusable.
I deleted the ini file in the AppData location for EDDF (that pointed to the stock file) and created a new ini file in EDDF\Scenery pointing to the AFCAD location in AFD\Scenery but GSX still uses the stock scenery.
I added AFD\Scenery to the active scenery library (not recommended by Aerosoft) and GSX failed to launch or appear in Addon Menu.
I have searched this forum for answer, and there are other posts, but I am surprised I seem to be only one with this problem. I've run to the end of my knowledge here and appreciate suggestions.
Thank you,

EDIT
Update to this topic: I copied the AFCAD from \Aerosoft\AFD\Scenery to the EDDF\Scenery folder. This works now, GSX is using the addon AFCAD instead of stock airport and P3D is okay with this arrangement. In fact, I append OFF to the AFCAD bgl file in AFD\Scenery and all is still good. P3D is using the AFCAD in the EDDF\Scenery location (easy to tell because stock airport is missing a runway). I have no idea what Aerosoft or SimWings is thinking with this Aerosoft\AFD business but I find it a nuisance. All good with GSX for now.
