Don’t get confused: Just because DxDiag says you have DX11 it doesn’t mean automatically you really have it.
It all depends on your graphics card and unfortunately this card seems to be reeeeeally old… According to this sheet, it doesn’t have any Shader Model (Unity needs atleast Shader Model 2): http://www.intel.com/support/graphics/sb/CS-033757.htm
Also your card has only 30MB video ram, which wouldn’t be really enough to run Unity properly at all.
I used to have the same problem but i managed to emulate shader model 2. I dont remember from where i got it but it worked, try searching it on google.
Hmmm, so i did some research and I found out two programs that can emulate shader model 2.0. Swiftshade and 3DAnalyzer are the ones I discovered. Would you happen to remember if one of these was the one you used? And if so, can you give me some more details, as I am a bit confused on emulating the SM 2.0. Any details or information at all would me much appreciated.
Just found Swift Shader to use on my laptop (Intel 945M chipset) and it dows allow Unity 4.3 to run while the laptop itself doesn’t support shader 3.0. Perhaps worth to try for you as well?
Success! Swiftshader did the trick! I have sucessfully emulated Shader Model 2.0 on Unity 4.2.2 with the Intel 82852/82855 GM/GME Graphics Controller!!
Thank you all so much for your help and if anyone wants more info on how to do it, go ahead and post here. Thanks once again to everyone!
