When you try to install Exchange Server 2007 Service Pack 2 (SP2) on a server that is running Windows Small Business Server 2008, the installation process does not start, and you receive the following error message:
Error: You must update your Windows Small Business Server 2008 settings both before and after you install Exchange Server 2007 Service Pack 2 (SP2). Before installing SP2 for Exchange Server 2007, read the detailed information at http://go.microsoft.com/fwlink/?LinkId=155135.
This problem occurs because the Exchange Best Practice Analyzer prevents Exchange Server 2007 SP2 from being installed on the server. To resolve this, you can follow the link that is in the error message to manually install Exchange Server 2007 SP2 or you can use the Microsoft Exchange Server 2007 SP2 Installation Tool for Windows Small Business Server 2008.
For the link to download the tool and the steps to use it, please see KB 974271.

Thank you for the post. FYI, it appears that MSI Installer 4.5 package will not install on my SBS 2008 system. I'm not sure if it is already there or not(maybe it isn't even required), but I get an error message when I try to install it saying, "The package does not apply to your system."
We recommend that you perform a full backup of the data on the computer that is running Windows Small Business Server 2008 before you install Exchange Server 2007 SP2. The reason for the backup is that you cannot uninstall Exchange Server 2007 SP2.
