Tried to install manually in FSX by pointing installer to desktop file, then extracting contents to Addon Scenery folder (copy/paste), and putting latest viva.dll in Heron's Nest scenery folder.
I just did not run the SODE.exe - not sure if it's compatible with Orbx peopleflow (or whatever they use), or if it's going to cause any issues with other Orbx Global, Vector, Open LC NA , or REX Essentials textures.
Where did the asphalt rwy in the water come from, anyway ?
What a mess buffet !
