Apologies if this is an inane question, but if my iMac i7 already runs Windows 7 beautifully, do I need to install the Boot Camp Software Update 3.1 for Windows 64? My main reason for asking, the updater does not work for me. I ran it as an Admin, in various compatibility modes, and still no dice. It asks if I want to run Internet-based software, I say YES, then...nothing. I utilized the driver workarounds when I initially installed Windows 7 to avoid the Black Screen O'Death and since then I have had zero issues. Other than an itchy desire to want the latest versions of everything, do you my Mac Brethren believe I should just live well enough alone? Color me flummoxed.
