As a couple of others have mentioned previously, for those who may have missed it, it's quite easy to bypass the version check for Boot Camp 6.0.
1. Download the Boot Camp 6 drivers from a supported Mac using the Download Only function in Apple Software Update. Or find it online somewhere, if it exists.
2. Extract the downloaded file using an application like 7zip
3. Open Command Prompt as an admin and use the cd function to navigate to "C:\*path to wherever you extracted the file from ASU*\AppleBcUpdate\BootCamp\Drivers\Apple"
4. Type msiexec /i BootCamp and hit return. The installer should appear and BootCamp 6.0 will proceed to install.
Confirmed working on Early 2011 17" MacBook Pro.
