FSX - scenery add-ons problem

i don't remember if that needs to be configured, maybe you need to poin it to FSX folder, i'm not sure. Jusr start it and see if configurator can see your sceneries. Go through text editor, group view and list and see if there are some errors displayed on the right hand side. If you have duplicated sceneries, this tool will suggest you to delete one of them, just check what you want to delete. 

You can add, enable or disable scenery areas etc

it gives me Errors = 0 , and there is no duplicated sceneries
