Microsoft Exchange Server 2007 setup can't continue because its attempt to install the Client Access Server or Edge Transport server roles failed because the COM+ Event System service isn't started on the target computer.
Exchange 2007 setup requires the computer that you're 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'
Right-click My Computer, and then click Manage.
Expand the Services and Applications node, and then click the Services node.
In the right pane, locate the Com+ Event System.
Right-click Com+ Event System, and then click Properties.
Set the Startup Type to Automatic and the Service status to Started.
Click Apply, and then click OK.
