Hello,
I installed it already before. MSFS recognizes it as installed but still when I start from KORS in the game the default airport is shown - not the Orbx scenery.
Btw, your central-guide doesn't specifiy how to install a scenery in MSFS 2020 but only for previous version or for other sims.
This is where I installed it:
E:\Orbx Librabry\msfs\KORS Orcas Island Airport
MSFS is installed on a separate SSd, same SSD the Orbx folder is located.
Do I have to save the Orbx scenery into a different folder?
