And it says, 

UPDATE: If you are unsure, please download GPU Caps Viewer (I recommend the portable version) to determine if you have a compatible video device and a working version of OpenCL installed. If you are using an AMD/ATI card you likely need to install the ATI APP SDK (make sure you obtain the correct version for 32/64-bit Windows).

I've downloaded the SDK and installed it, but it's just sitting on my hd, doing nothing at all. I seem to be mining bit coins ok. Soft of confused as to what's going on? Thanks

user141: If you are mining bitcoins successfully, then don't worry about it.
There's no need to install the SDK. OpenCL drivers are included with AMD's Catalyst drivers.
Also note that solomining on a GPU could mean you never make a single coin. It may look like now that it will take a couple years, but by that time the difficulty is much higher. Unless you are very lucky, you may never get anything at all. Try mining in a pool instead and think about getting ASIC.
