Not able to run the sample code in GPU.

I have been installing like 10 times today different versions of ATI catalyst. I have windows 7 ATI Mobility Radeon HD 5470. Downloaded 11-2_mobility_vista_win7_32-64_ccc.exe and  ati-stream-sdk-v2.3-vista-win7-64.exe files from download section of amd website and installed on my system.

I tried running the CAL sample file FindNumDevices and CLinfo. I am getting

Supported CAL Runtime Version: 1.3.185
Found CAL Runtime Version: 1.4.519
Use -? for help

These are the outputs that I m getting from running these samples. I have been struggling with this for a long time and couldnt find any document relating to this.

Any help in making the sample code in GPU will be greatly appreciated.

Thanks
