I have successfully been able to download and install Windows 7 using Bootcamp but I am unable to connect to the internet using a wireless connection. I'm having trouble installing the required drivers to the Windows 7 side of my bootcamp partition. I keep getting the error message: "Boot camp x64 is unsupported on this computer model." I have a Macbook Pro (Version 10.8.2) that came with a Lion download instead of a disk. Without the drivers, I am unable to use the Apple trackpad fully and the only option for a network connection is through ethernet in Windows 7. No wireless option available. I might also add that I still have the disk from Snow Leopard just in case I needed a backup.
You have to purchase 32-bit Windows 7 version
