As said in the Subject, I cannot install the AMD APP SDK, therefore I stuck mining with CPU with a flimsy 2 Mh/s :/ whenever I open the installer, I get into the catalyst install manager, click next, click install and then 'Catalyst install manager has stopped working' it's also the same when I try and install new drivers for my card (although I did that through windows update and it worked). I have an ATI 4870 if that helps. I don't know what to do any help will be appreciated
