32-bit lightmass compile

So using Visual Studio 2013 Professional, I can’t seem to compile the unreal lightmass and swarm agent for 32 bit. The documentation says that the editor must be compiled in 64 bit, but I see no reason why I shouldn’t be able to compile lightmass. Any ideas? I need this because I have a lot of computers but most of them are 32 bit and I distribute the lightmass work to multiple computers.
