I intalled catalyst 11.4 and sdk 2.4

If you are have trouble getting an answer here, you might try in Community, Message Boards, Number Crunching.. a lot of brain matter shows up there.

It looks like you don't have the apps installed to run the GPU WU's. Try using the Lunatics unified installer version 0.38 . it has the ATI GPU apps that you'll need.

You'll also want to back down to the ATI driver version 11.2 . Versions after 11.2 push work back onto the CPU which slows your GPU and CPU WU's down.
