http://www.simviation.com/simviation/?t ... 60&page=93I've downloaded the 777 to check it out. This one is configured slightly differently from the C-5M & Posky 747. The
'aircraft container' folder is hidden inside another folder. (The
'aircraft container' folder is the folder
directly containing the Model, Panel, Sound & Texture sub-folders.) See this shot.

To install the 777 paste the folder named
777-300AA into your FSX SimObjects\airplanes folder. You will get a message about verifying a gauge. Click Yes. (This will only need doing once.)
Whoever configured this file made a typo in the aliased Sound.cfg which means the aircraft will have no sound.

Here's your 777 in FSX.
the c5m super galaxy canadian air force is not in the military downloads for fsx.
I already have the C-5M. I've given detailed instructions on installing it in two previous replies. I can't explain it any more clearly. I'll repeat it again.
To install the aircraft to FSX paste the C-5M folder I've marked with a red arrow into your FSX\SimObjects\airplanes folder. That's all there is to it.
