Alright, after looking around a bit more, it seems that Boost automatically builds 32-bit libraries by default(I.E. by launching b2.exe via Windows Explorer). I had to use the command prompt, changed the current working directory to the Boost directory(I.E. C:\local\boost_1_64_0) and executed "b2.exe --toolset=msvc address-model=64 --build-type=complete". I was then able to compile without any errors.
Perhaps this is something that could be included in the installation instructions for TrinityCore?
