Some Services stop automatically if they are not in use by other services

Error "SOME SERVICES STOP AUTOMATICALLY IF THEY ARE NOT IN USE BY OTHER SERVICES" while trying to start a windows service.

I have a service that does not use the windows service config file and uses static properties - it works fine

Now, i make use of app.config file and rebuild my setup project + the service project. Now i install the service and then try to start the service - i get the following error:

SOME SERVICES STOP AUTOMATICALLY IF THEY ARE NOT IN USE BY OTHER SERVICES

Service logs on as local system.

Any input is welcome please! Thanks.
