I just installed a new hard drive in my early 2011 MacBook Pro and when I installed windows 7 ultimate 64 bit through bootcamp I tried installing the drivers and it keeps giving me an error everytime I try to double click on setup.exe saying "the version of this file is not compatible with the version of windows you're running" even though they are the correct bootcamp drivers for the operating system. I have tried running it in administrator mode and compatibility mode both to no avail. I'm at my wits end. Please help!
