Hi, Only Exchange 2007 SP1 is supported on a windows server 2008 so you must download the service pack and install this instead of the one you are trying to install. Leif

Hi Sean, Leif have answered your question. You need Exchange 2007 SP1. You can see it from the link below: Exchange 2007 System Requirements http://technet.microsoft.com/en-us/library/aa996719(EXCHG.80).aspx Regards, Elvis
