Hello there,
I think you installed the wrong software. In order to run an OpenCL application, you will need to install the OpenCL driver. By my understanding the AMD APP SDK is just that: A software development kit. The needed driver comes with the Catalyst Software Suite, but even then I'm not quite sure if it will work because I can not find any information on wether or not your GPU is capable of doing OpenCL. From the information on the manufacturers page I would rather say no, but there are some other sources with different opinions, so I think you will have to try it out.
