I have to put Windows on my computer (get this - only because I have to run Explorer). I am going to do this using Parallels.
From what I can see on the Microsoft web site, they only sell upgrade versions of Windows 8. So I am left with getting a non-upgrade version of Windows 7. I see that Windows 7 comes in two flavors: 32 bit and 64 bit. Which one do I want? I have a 15 inch late 2011 MacBook Pro with a 2.2 GHz i7 (4GB 1333 MHz DDR3).
