Hi guys,
I recently downloaded Gui miner, to try it out
The problem is I always get this screen

I can't choose any other device

My guess is you need to install an OpenCL package from your GPU vendor (assuming your GPU supports it, of course). Something like GPU Caps viewer can help you determine that if you are unsure yourself.
