Applies to: Exchange Server 2007 SP1, Exchange Server 2007

Topic Last Modified: 2007-08-13

This topic provides information about how to troubleshoot Microsoft Exchange Server 2007 Setup if Setup fails with the following error when it starts to copy Exchange 2007 files: "The Windows Installer service could not be accessed. This can occur if you are running Windows in safe mode, or if the Windows Installer is not correctly installed." You can find this error in the ExchangeSetup.log file. The ExchangeSetup.log file is located at %systemdrive%\ExchangeSetupLogs.

This issue occurs when the Microsoft Windows Installer service is disabled, when you are running Windows in safe mode, or when the Windows Installer is not correctly installed.

To resolve the problem, perform one or more of the following tasks:

  • Enable the Windows Installer service. For detailed steps, see the procedure later in this topic.

  • If you are running Windows in safe mode, restart Windows and run in a mode other than safe mode.

  • Reinstall the Windows Installer. For more information, see Download details: Windows Installer 3.1. Redistributable.

To perform this procedure, the account you use must be delegated the following:

  • Membership in the local Administrators group
