BIAB is a 32-bit application. There are actually not that many 64-bit applications available for Windows yet, but that of course changes every day as more and more vendors are creating them.

BIAB can use multiple cores from your processor, but that works whether you run the 32-bit version of Windows or the 64-bit version.

You are correct that BIAB won't use 12GB of RAM (32-bit can only address a little less than 4GB); however, BIAB doesn't use anywhere close to 12GB of RAM to run, much less 4GB. The 12GB does give you additional memory for other concurrent applications, however.
