I'm using Windows 7 (64-bit) and want to use AMD's OpenCL library. I installed the correct driver and the Stream SDK v2.0-beta4. My problem was that if I start a program after a few seconds the machine freezed. A few seconds later Windows showed the message "Display driver stopped responding and has recovered" and the program was not executed successfully.
In case somebody of you has the same error here's a possible solution: Install the "ATI PCI Express (3GIO) Filter Driver". Unfortunately it seems like that AMD doesn't provide this driver anymore. It would be nice if someone has further information about obtaining this package.
Best regards, Björn
