You are free to mix the 32 and 64 bit installations across multiple machines on the network and they can interoperate without issue, so just install the appropriate version that matches the 'bitness' of the operating system. The only limitation is that you cannot install both the 32 bit and 64 bit version on the same machine at the same time.

Hope that helps
