Its a standalone program. I take Little Nav Map and create a folder on “C” called Little NavMap and then I take the folder beginning with the file named “bearer” and copy the entire file and put it in the folder. You take take the “exe” right click and “pin to taskbar” and that way you can launch. When it launches then go to scenery library and load scenery library . You’re good to go. Also 2.8.3 beta just came out
Hope this helps
