Error message when you try to install Exchange Server 2007: "The image file <path>\setup.exe is valid, but is for a machine type other than the current machine"

When you try to install Microsoft Exchange Server 2007, you receive the following error message:You receive this error message immediately after you start the Setup.exe program or the Setup.com program.

This issue occurs if you try to install the 64-bit version of Exchange 2007 on a computer that has a 32-bit computer operating system.

To resolve this issue, install Exchange 2007 on a computer that has an x64-based version of Microsoft Windows. Or, if you want to install only the Exchange 2007 administration tools, or if you want only to prepare the Active Directory directory service for the installation of Exchange 2007, obtain the 32-bit version of Exchange 2007.

The 64-bit version of Exchange 2007 is supported for use in a production environment. We provide the 32-bit version of Exchange 2007 only for testing and for training. The 32-bit version of Exchange 2007 is not supported in a production environment.

However, we do support the 32-bit version of Exchange 2007 for the following uses in a production environment:

• We support using the 32-bit version of Exchange 2007 to prepare Active Directory for the installation of Exchange 2007.
• We support using the 32-bit version of Exchange 2007 for the Admin-only role installation option. This option lets you run Exchange 2007 on a 32-bit system so that you can administer Exchange 2007 from a 32-bit Microsoft Windows XP-based computer or from a 32-bit Microsoft Windows Server 2003-based computer.
