Vista x86 SP 2, Nvidia video card (only running the CPU component of Ati Stream). The VectorAdd sample fails in the CreateContextFromType call with the following exception:

Further testing using Ati's own samples reveals the following error:

---------------------------
AESEncryptDecrypt.exe - Unable To Locate Component
---------------------------
This application has failed to start because aticalcl.dll was not found. Re-installing the application may fix this problem.

This is an upstream issue that will be fixed in a future Ati Stream release: http://forums.amd.com/forum/messageview.cfm?catid=390&threadid=120308#10...

It only affects the Ati implementation when running on non-Ati hardware (or Ati hardware without the OpenCL GPU drivers installed).
