There are two entries in the eventviewer:
first in the application part:

Service cannot be started. System.IO.FileNotFoundException: Could not load file or assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.
File name: 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
at TvScheduler.WindowsService.TvSchedulerService.OnSt art(String[] args)
at System.ServiceProcess.ServiceBase.ServiceQueuedMai nCallback(Object state)

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

then the system part:
both messages issued by the Service Control Manager

Maybe as a side note (should have said that way earlier): I am running windows x64

hope that helps
