Yeah I agree, Sony should be ashamed. If they won't let AMD support their card it is a disgrace that they won't update the drivers themselves!
There is no error with the installer, it just detects I have a sony vaio before it'll unpack and then refuse to continue the installation. What bugs me is that I know there are generic drivers in the package which I could use and install separately if I could just get at the files.
You used to be able to get around this as ccc would unpack the files first and then refuse to continue, but you'd still have access to the drivers. But the latest versions of ccc will run the diagnostic first before the unpack
But yeah, if you want to play games a sony laptop is a crappy choice, I wish I knew this before I bought it, but I've had it for a few years now and I guess it is time to upgrade, maybe I'll put together a proper desktop computer.
I've asked around on a few other forums, If I get any answers I'll post them here just in case anyone else has the same problem as me.
