Service Install Problem

Hi,

Trying to install a service (which does nothing at yet), I recieve the following error using the installutil.exe app.

The text in bold is the important information I think......

The appliation is not running in the Services Panel.

Can any one shed any light on whats going on?

This is interesting. My co-worker just uninstalled my service (at the client location), then when he tried to reinstall the service he got the same error. I haven't been able to figure it out either. Although, he did eventually get it to work by using the MSI installer rather than the setup.exe installer.

This may or may not help, but I have found that if the management console is open after you have uninstalled a service, it does not fully uninstall but merely marks it for deletion. If you close the management console then it gets fully deleted.....

Hi,

A few things.... I think my code (maybe bad code) created an event log (separate to Application/Security/System) the first time it was run.. subsequent un-install did not remove this, and a new install tried to create it again, hence the error.

The thing is.. you can't remove this from the event viewer, but can delete it from the Server Explorer within Studio.

New installs have not created this log again.. strange.

I have found that I need to restart the computer after uninstalls to "release" the objects otherwiae I am ot able to rebuild the application.

Thanks for your time.

The code I used to create the Event log was...
' Event Log Initilisation
If Not EventLog.SourceExists("HL7MessageQueueService") Then
EventLog.CreateEventSource("HL7MessageQueueService", "HL7MessageQueueServiceLog")
End If

EventLog.Source = "HL7MessageQueueService"
EventLog.Log = "HL7MessageQueueServiceLog"

and on service start...

EventLog.WriteEntry("The service was Started (in OnStart method).")
