Aircraft install problem

Hope someone can help. I have installed three aircraft so far and installed them according to the instruction in the readme. They aircraft are loadable, and flyable but does not load any exterior texture, and two of them failed to load interiors as well. Does anyone have any idea how I can get this fixed thanks.

Go into the graphic tab ion FSX settings and uncheck DX10, the textures should come back.

Thanks for you help.
