thanks a lot my friend
i do it, and i create the bat file but when I click on Run.bat a black window flashes up and then disappears!!
you sound like your in windows. you need the kernel. add ".exe" on the end of your cpuminer in that bat file try again

if that dosent work open a cmd window in the folder with the bat and drag and drop it into there and hit enter should work

hope tht helps!
