Microsoft Exchange Server 2007 setup cannot continue because its attempt to install the Client Access Server or Edge Transport server roles failed because the COM+ Event System service is not started on the target computer.

Exchange 2007 setup requires the computer that you are installing Microsoft Exchange to have the COM+ Event System service status set to Started.

The COM+ Event System service supports system event notification for COM+ components, which provide automatic distribution of events to subscribing COM components.

Both the Client Access Server and Edge Transport server roles have dependencies on COM+ components that subscribe to the COM+ Event System service.

To resolve this issue, verify that the COM+ Event System service status is set to Started on the local computer, and then rerun Microsoft Exchange setup.

To set the status of the COM+ Event System service to 'Started'
  1. Right-click My Computer, and then click Manage.

  2. Expand the Services and Applications node, and then click the Services node.

  3. In the right pane, locate the Com+ Event System.

  4. Right-click Com+ Event System, and then click Properties.

  5. Set the Startup Type to Automatic and the Service status to Started.

  6. Click Apply, and then click OK.
