Error Code 1062 = The service has not been started

I am trying to run a build of OCS Windows Agent 2.3.1.1. I am getting this when I press "Run OCS Inventory NG Agent Now" I get this: 
Error Code 1062 = The service has not been started

I know that the service has the stopped state but why it is not starting ? What could be wrong here ??
 Secondly, If I start the service manually then on pressing "Show Inventory Information":

Failed sending control message to OCS Inventory Service... Error code 109 = The pipe has been ended


Secondly, I don't know can this be a problem with an External Dependencies ?
Any help in this regard will be appreciated...
