ATI Catalyst Mobility cannot be downloaded due to incompatible hardware...

I have a HP Dv6-6135dx pavilion laptop.
It has a switchable graphics AMD 6620G and an AMD 6750M. I realized my games were struggling. So I went to check the graphics properties by left clicking and finding it on Catalyst Control Center. Every time I that it says that my computer doesn't have a proper AMD driver or that I don't have the graphic adapter on my computer. Control panel sees both, recognizes both, and says they are both running fine. I checked the performance on the two cards, there was nothing being run through the 6750m. 
I tried to update it and I install the latest mobility suite that has the newest drivers (or any drivers), but when it tries to install/update it agains says ATI Catalyst Mobility cannot be downloaded due to incompatible hardware. Install the correct driver... Gfx adapter not connected.

It also has an A8-3500M APU with radeon hd graphics.... That won't update either, I get an "error can't rewrite catalyst/mobility/ATIMMcDNAld.MSI. 

I went to HP and they had a BIOS update.... Did that, didn't change anything. Also installed catalyst control center/gfx drivers from HP for this computer... They sucessfully installed but changed nothing.

I uninstalled and reinstalled the drivers on both the 6620G and the 6750m. No change.

I am running Windows 7 64-Bit.

I have no idea what to do... Any ideas?

Have you tried to assign the game with high performance setting in the control panel?
