Yes, the 64 bit build won't run on a 32 bit OS.

It depends on how much RAM you need to run your computations, i.e. if
the machines have less than 3 or 4GB RAM the benefit of more RAM
address space due to 64 bit isn't there. 32 bit code is smaller and in
many cases runs about as fast as 64 bit code. There are exceptions in
either direction, so if you told us what you wanted to do we could
give you some more pointed advice.
