I need driver for my discrete video

In my laptop HP pavilion dv7 6001er two videos (screen 1). When I play Overwatch it always freezes and I have to reboot my laptop. On OW forum they recommended me to update my discrete drivers, because it's too old(screen 2). I tried to install Radeon Software Crimson Edition 16.2.1 Beta, but there is an error(screen 3). I tried to install Catalyst Software Suite 15.7.1 but it didn't change anything.

I don't know what to do
