When you have multiple platforms installed, Stream Kernel Analyzer will not be able to create a context to a CPU device, unless the ATI Stream platform is enumerated 1st.
This is a bug report, not sure how to post one, so decided I'll post a message here in hope it'll get to the right eyes.
You can report nugs here as AMD Developers regularly visit the forums.
Can you please explain the problem in more detail. Also mention the system configuration : CPU, GPU(s), SDK,Catalyst and OS.
