No GPU, Samples don't work on CPU

Hello

I have CPU Intel Celeron 336 with MMX, SSE, SSE2, SSE3, EM64T instruction. Windows XP SP3 x86. ATI Stream SDK 2.2. As I have read it must be sufficient for OpenCL to work.

"C:\Program Files\ATI Stream\bin\x86\CLInfo.exe" work fine (see attached code).

But "C\Program Files\ATI Stream\samples\opencl\bin\x86\HelloCL.exe" and other samples return an error:

stdout: HelloCL!
stdout: Getting Platform Information
stderr: Platform::get() failed (-1001)
