Install window services

Question

Hi I'm new in this Forums. So I dont know thios is is the right place to post my message or not. In my application I want to send mail on every weekend. So I created one window service. It builds successfully and I created service using installutil. But now when I'm trying to start my service, it automatically stops. and showing the error message like "The EService service on local computer started and then stopped. Some services stop automatically if they have no work to do, for example, the performance Logs and Alerts service", can any one tell me how to resolve this.
