I am running Win8 on bootcamp on the MBP. Everything works except the multitouch trackpad on the MBP. There is software to make this work. I am running Lion. However, it says I need driver updates 4.0 from bootcamp which I cannot locate to install. Can someone point me to the Bootcamp 4.0 for 64 bit drivers update? Every search I do comes up with "requirements" but not an actual link to the updates and it is not on my Snow Leopard disc. Lion does not come with a dics.
