When i try to download th b777 for flightgear 2017.1.2 Windows it doesn't work.
It says it's downloading but when i finishes I get the message: "An error occured installing the aircraft Boeing 777-200: invalid checksum"
It gives me an update button on the aircraft but i can't press it and when i restart the sim the aircraft vanishes
I've tried downloading it 3 times from the default hangar
Edit:tried a manual download and it worked but i still can't luanch it. Same for every plane I've tried except the 757
