Classic is working fine but for RTC as i try to start my service it gives an error
"The Microsoft Dynamics NAV Business Web Services 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."
I tried using adminstrator user account, local system account and as network service but its not getting started.
Try to check the Windows application log for more details on why the service failed to start. By looking at the error you got during the install, it sounds as though your user account does not have permission to start services on the server regardless of which credentials your service is running under.
In C drive Service folder is not installed and If I try to install Service manually it is displaying
