    <description>&lt;P&gt;Hello,&lt;/P&gt;

&lt;P&gt;I am working on an open source jpeg 2000 decoder:&lt;/P&gt;

&lt;P&gt;&lt;SPAN style="font-size: 1em; line-height: 1.5;"&gt;&lt;A href="https://github.com/OpenCodec/ThousandthChicken" target="_blank"&gt;https://github.com/OpenCodec/ThousandthChicken&lt;/A&gt;&lt;/SPAN&gt;&lt;/P&gt;

&lt;P&gt;I am on windows, using visual studio 2012 and the 2014 beta OpenCL sdk.&lt;/P&gt;

&lt;P&gt;&lt;SPAN style="font-size: 1em; line-height: 1.5;"&gt;My laptop has an intel CPU and an HD4400 intel GPU. &amp;nbsp;When I target the CPU,&lt;/SPAN&gt;&lt;/P&gt;

&lt;P&gt;&lt;SPAN style="font-size: 1em; line-height: 1.5;"&gt;everything works fine. But, when I target the GPU, clBuildProgram crashes with an access&lt;/SPAN&gt;&lt;/P&gt;

&lt;P&gt;&lt;SPAN style="font-size: 1em; line-height: 1.5;"&gt;violation. &amp;nbsp;&lt;/SPAN&gt;&lt;/P&gt;

&lt;P&gt;&lt;SPAN style="font-size: 1em; line-height: 1.5;"&gt;Thanks,&lt;/SPAN&gt;&lt;/P&gt;

&lt;P&gt;I was able to build and run your application on my HD4400 graphics without issues (I didn't have the source jp2 file but downloaded a file and modified your source). The fact that you weren't able to run the sample from the SDK tells me that the runtime is probably not installed correctly.&lt;/P&gt;

&lt;P&gt;What version of the gfx driver do you have? Can you update the driver and/or reinstall/repair the SDK and run the sample?&lt;/P&gt;

      <description>&lt;P&gt;Thanks, Raghu. I have switched to another machine that has an AMD graphics card; will try what you suggest&lt;/P&gt;

&lt;P&gt;if I switch back to the HD4400 machine.&lt;/P&gt;</description>
