I have spent the last 45 minutes or so using every search topic possible to try and clear up my confusion. I'm pretty sure there is a topic that I'm not getting to, but I'm pretty stuck, so I figured I would just go ahead and ask. Okay. So... (obviously) I want to bootcamp. I am currently running Lion 10.7.5 on my Mid-2011 iMac. I have 4 GB of RAM. My version of Bootcamp is 4.0.4, according to the version section of the Get Info option on it. Where I'm confused is that some places I've heard I can only install the 32bit version of Windows 7, and other places I've read that I can install the 64bit. I would rather install the 64bit so I can make use of the RAM, obviously. Help.
