Connot find simulator

when i open the navdada installer

Hi,
I assume you have the sim from the MarketStore … correct? Or do you have a Steam Version?

Can you check, if this folder exists:
%localAppData%\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache

… or, if this folder exists:
%appData%\Microsoft Flight Simulator

… or does both folder exists?

Cheers,
Richard
