Hi I have Windows 7 running via Bootcamp and it works great. However I want to install the latest ATI drivers for my 27" iMac (late 2010 model I believe, but I got it start of this year), it has an ATI Radeon HD 5750 (doesn't apple use the mobile versions?). Anyway, I have tried downloading the mobile and desktop drivers from the AMD website and this is what heppens: Run the .exe I get, it extracts all setup files and things, then I get a little Catalyst' splash screen. After that I get a window asking for my language of choice, press next and it says, Install or Uninstall, so I when I click either of them, the window dissapears and nothing happens. Please help! Thanks.
