Need help install drivers for windows (bootcamp)

[xxRONNIExx]

Okay so I install win 7 through bootcamp using an external driver. Everything seemed to be in working order until I booted up windows 7. I cant get a wifi connection. Did a little research and found out that I have to install boot camp driver for windows using the MAC OSX disc.
Once I try to run the disc (setup.exe) I get a "Boot camp x64 is unsupported on this computer model".
I have a new 11" 4GB Macbook Air. Can anhyone help me out? Thanks
