Hello, I reinstalled Windows 7 Enterprise 64-bit on my MacBook Pro Retina Display 15" due to some unstable problems with Windows. For unknown reason, I could not download the drivers via Bootcamp Assistant. Instead, I went to Apple Support page to download BootCamp 5.0.5033. After installation, the function keys for volumn control work but those for brightness control (F1 and F2) are not working. Any way to fix this problem? Thanks.
