Ive been having the exact same problem. I tried following the instructions listed above but I am met with the same response with the Catalyst program (wrong software/hardware). This is happening despite a successful download of the latest driver from the HP website. I also have an HP Envy 15 and there is great inconsistency with performance, most likely due to the complications with the switchable graphics. Some things run great, others barely at all. Please help! Thanks!
