Help getting flight sim x to work on windows 7 no vidioe

are you sure that you installed the game correctly? what is your machine spec?

without system specs, it's near impossible to tell what the problem could be. But, to start with, I'd say to make sure your graphics chip is capable of direct-x 9, if it can not use dx9, then fsx will not work unless you get a new graphics card. If it can use dx9, make sure you have the most current drivers for your hardware.
