Title Body

I am having difficulty reliably creating / removing event sources during the installation of my .Net Windows Service. Here is the code from my ProjectInstaller class: // Create Process Installer ServiceProcessInstaller spi = new ServiceProcessInstaller(); spi.Account = ServiceAccount.LocalSystem; // Create Service ServiceInstaller si = new ServiceInstaller(); si.ServiceName = Facade.GetServiceName(); si.Description = "Processes ..."; si.DisplayName = "Auto Checkout"; si.StartType = ServiceStartMode.Automatic; // Remove Event Source if already there if (EventLog.SourceExists("AutoCheckout")) EventLog.DeleteEventSource("AutoCheckout"); // Create Event Source and Event Log EventLogInstaller log = new EventLogInstaller(); log.Source = "AutoCheckout"; log.Log = "AutoCheckoutLog"; Installers.AddRange(new Installer[] { spi, si, log }); The facade methods referenced just return the strings for the name of the log, service, etc. This code works most of the time, but recently after installing I started getting my log entries showing up in the Application Log instead of the custom log. And the following errors are in the log as well: The description for Event ID ( 0 ) in Source ( AutoCheckout ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. For some reason it either isn't properly removing the source during the uninstall or it isn't creating it during the install. Any help with best practices here is appreciated. Thanks! In addition, here is a sample of how I am writing exceptions to the log: // Write to Log EventLog.WriteEntry(Facade.GetEventLogSource(), errorDetails, EventLogEntryType.Error, 99); <str
