sorry for not specific path is appdata-romming-virtuali-gsx- inside gsx has to creat MSFS folder beacuse the software not installing
You are not supposed to have this folder, unless you start customizing airports.
EDITYes, you are absolutely right! It's normal this folder wouldn't exists on a clean install, because it's created only when you first customize a scenery, but for some reason, if it's not there, it will give the "no parkings" error.
So yes, the temporary solution is to create this empty folder:
%APPDATA%\Virtuali\GSX\MSFS
But since we identified it now, a proper fix will appear very soon.
