Windows 7: Can't install driver for HD6520G

I recently reinstalled Windows 7 and I had to install all my drivers. Both my gpu's were listed in device manager as standard vga graphics adapter.



I tried installing the driver from the Acer website, but that only installed the driver for the HD 7470M. This was the same for the drivers from the AMD website.

I also tried the auto detect app from the AMD website and that detects my CPU and integrated 6520G, but when I try to install the driver, no display driver is installed.

I tried to uninstall the driver for the 7470M so only the 6520G was listed in device manager, but the result was the same.

I don't know what else I could do, so any help is welcome.

I also reported this to Acer and AMD and Acer says they can't do anything because I changed the OS from Home Premium to Ultimate...

Amd says Acer should provide all the drivers. So now I'm stuck and reverting back to home premium.

Can I copy the drivers from the windows directory and paste them in the system32 and syswow 64 folders after I install ultimate?
