So, I installed Windows 7 x64, figuring that Apple would allow me to install the 64 bit drivers on my Macbook. I was wrong.

When you insert the (snow) Leopard DVD, it gives you a message along the lines of “you don’t own an expensive enough Mac to use 64 bit Windows”. So, with a little fancy Googling, I found a workaround.

It is confirmed working with the Snow Leopard DVD also.

Open the start menu and type in “cmd”. Right click on the result and select run as administrator.

Then type in:

D:

cd “Boot Camp\Drivers\Apple”

msiexec /i BootCamp64.msi

There! If you have done everything correctly, you should be on your way to installing the 64 bit drivers!
