IPB will work on any server as long as it has a Web Serving program (Apache, Litespeed, Lighty, IIS), PHP and MySQL/MSSQL installed. They can run on 64 bit systems which allow for more memory (RAM) to be used by the server. As mentioned however, since IPB is programmed in PHP, it cannot itself be optimised for either 64bit or 32bit systems, however, PHP could.
