I am using the code below in AftferInstall even in a windows service project.I have cretaed a setup and when i install the project i get an exception "An exception occured in OnAfterInstall event handler of System.ServiceProcess.ServiceInstaller. - > Not found"

when the remove the code below then the service installs fine.So there is some problem with code below.Here serviceController is the component that i placed from toolbox

ConnectionOptions coOptions = new ConnectionOptions();    coOptions.Impersonation = ImpersonationLevel.Impersonate;    ManagementScope mgmtScope = new System.Management.ManagementScope(@"root\CIMV2", coOptions);    mgmtScope.Connect();    ManagementObject wmiService;    wmiService = new ManagementObject("Win32_Service.Name='" + serviceController.ServiceName + "'");    ManagementBaseObject InParam = wmiService.GetMethodParameters("Change");    InParam["DesktopInteract"] = true;    ManagementBaseObject OutParam = wmiService.InvokeMethod("Change", InParam, null);    serviceController.Start();
