Hi Can you try to run the topology preparation steps manually? http://technet.microsoft.com/en-us/library/bb288907%28EXCHG.80%29.aspx System requirements http://technet.microsoft.com/en-us/library/aa996719%28EXCHG.80%29.aspx Jonas Andersson | Microsoft Community Contributor Award 2011 | MCITP: EMA 2007/2010 | Blog: http://www.testlabs.se/blog | Follow me on twitter: jonand82

If the version of Exchange and the O/S are in the supportability matrix, try running the installation using "Run as administrator". Having administrative rights and actually being the administrator aren't quite the same. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi This third service pack for Exchange 2007 enables Exchange 2007 to be installed on the Windows Server 2008 R2 version of the operating system. You can download it from here and install it directly. http://www.microsoft.com/download/en/details.aspx?id=24111
