Hi !
You need to have a graphics card by NVIDIA or ATI/AMD to run CityEngine (preferred NVIDIA). Intel graphics cards are not supported.
Check this in your machine. It may be that you have one and that you have a second onboard graphics card to save battery power. In that case, make sure you have the latest graphics drivers and that the power options are set so that the secondary graphics card is never used.
Hope this helps for now.
Let me know ..
Matt
