Downgrading Bootcamp to version 4.0

[AugustusRomanus]

Hi, I have a Mac Pro 3,1 and I would like to install Windows 7 64 bit version with bootcamp, but version 5 does not allow me to, (see 'Mac Pro' tab http://support.apple.com/kb/ht5634 ). So, how do I downgrade to 4.0?

I believe bootcamp version is tied to the operating system version so unless you're willing to downgrade OSX there's no way to downgrade bootcamp
