Directx

Hi everyone
my os is vista 64bit pack1 and I installed DirectX SDK(10) on my system
but I cant compile this code an it returns :

hr=E_INVALIDARG


DXGI_SWAP_CHAIN_DESC swapchainDesc;
ZeroMemory(&swapchainDesc,sizeof(swapchainDesc));
swapchainDesc.BufferCount=1;
swapchainDesc.BufferDesc.Width=width;
swapchainDesc.BufferDesc.Height=height;
swapchainDesc.BufferDesc.Format=DXGI_FORMAT_R8G8B8A8_UNORM;
swapchainDesc.BufferDesc.*******Rate.Numerator=60;
swapchainDesc.BufferDesc.*******Rate.Denominator=1;
swapchainDesc.BufferUsage=DXGI_USAGE_RENDER_TARGET_OUTPUT;
swapchainDesc.OutputWindow=hWnd;
swapchainDesc.SampleDesc.Count=1;
swapchainDesc.SampleDesc.Quality=0;
swapchainDesc.Windowed=false;
HRESULT hr=D3D10CreateDeviceAndSwapChain(NULL,
D3D10_DRIVER_TYPE_REFERENCE,
NULL,
0,
D3D10_SDK_VERSION,
&swapchainDesc,
&pSwapChain,
&pD3DDevice);


on the callstack window it shows this message:

The application was compiled against and will only work with D3D10_SDK_VERSION (28), but the currently installed runtime is version (29).
Recompile the application against the appropriate SDK for the installed runtime.


I tired with examples of Directx but error is same.

how can I solve this problem?
