Server 2008 Standard with SP1 installed on 64-bit machine with 6gb of memory. I tried to install Exchange 2007 on it by beginning with setup /prepareAD. It starts and then stops by saying it cannot install on the operating system that is running. What gives?

HI, I am assuming you are trying to install Exchange 2007 RTM version on Windows 2008.I would like to let you know Exchange 2007 RTM version doesnt support to install on windows 2008.You need a minimum Exchange 2007 SP1 to install exchange on Windows 2008.Refer below TechNet article. "On Exchange 2007 RTM server, it is not supported to upgrade your operating system to Windows Server 2008, and then upgrade Exchange 2007 to SP1. To learn more about running Exchange 2007 on Windows Server 2008, see "Exchange 2007 and Windows Server 2008" in Exchange Server 2007: Platforms, Editions, and Versions.
