PRB: "Requested Registry Access Is Not Allowed" Error Message When ASP.NET Application Tries to Write New EventSource in the EventLog (329291)

RESOLUTION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. To resolve this problem, a user who has administrative rights must create the event source before you run the ASP.NET Web Application. To create an event source, use one of the following approaches.

First Approach

Create an event source under the Application event log in Registry Editor. To do this, follow these steps:

1. Click Start, and then click Run.
2. In the Open text box, type regedit.
3. Locate the following registry subkey:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application

4. Right-click the Application subkey, point to New, and then click Key.
5. Type TEST for the key name.
6. Close Registry Editor.

Second Approach

The EventLogInstaller class in the System.Diagnostics namespace permits you to install and configure an event log that your application reads from or writes to while running. You can create an event source by using EventLogInstaller. To do this, follow these steps:

1. Use Microsoft Visual Basic .NET or Microsoft Visual C# .NET to create a new Class Library named EventLogSourceInstaller. By default, the Class1.vb file or the Class1.cs file is created.
2. In Solution Explorer, right-click EventLogSourceInstaller, and then click Add References.
3. In the Add Reference dialog box, double-click System.Configuration.Install.dll, and then click OK.
4. Rename the Class1.vb\Class1.cs to MyEventLogInstaller.vb\MyEventLogInstaller.cs.
5. Replace the existing code in MyEventLogInstaller.vb or MyEventLogInstaller.cs with the following sample code:
   
   Visual Basic .NET Sample

   Imports System.Diagnostics
   Imports System.Configuration.Install
   Imports System.ComponentModel
   
   <RunInstaller(True)> _
   Public Class MyEventLogInstaller
       Inherits Installer
       Private myEventLogInstaller As EventLogInstaller
   
       Public Sub New()
           ' Create an instance of 'EventLogInstaller'.
           myEventLogInstaller = New EventLogInstaller()
           ' Set the 'Source' of the event log, to be created.
           myEventLogInstaller.Source = "TEST"
           ' Set the 'Log' that the source is created in.
           myEventLogInstaller.Log = "Application"
           ' Add myEventLogInstaller to 'InstallerCollection'.
           Installers.Add(myEventLogInstaller)
       End Sub 
   End Class 
   

   Visual C# .NET Sample

   using System;
   using System.Diagnostics;
   using System.ComponentModel;
   using System.Configuration.Install;
   
   
   namespace EventLogSourceInstaller 
   {
   	[RunInstaller(true)]
   	public class MyEventLogInstaller : Installer
   	{
   		private EventLogInstaller myEventLogInstaller;
   
   		public MyEventLogInstaller()
   		{
   			//Create Instance of EventLogInstaller
   			myEventLogInstaller = new EventLogInstaller();
   
   			// Set the Source of Event Log, to be created.
   			myEventLogInstaller.Source = "TEST";
   
   			// Set the Log that source is created in
   			myEventLogInstaller.Log = "Application";
   			
   			// Add myEventLogInstaller to the Installers Collection.
   			Installers.Add(myEventLogInstaller);
   		}
   	}
   }
   
   

6. On the Build menu, click Build Solution to create EventLogSourceInstaller.dll.
7. Open the Visual Studio .NET Command Prompt.
8. At the command prompt, change to the folder where EventLogSourceInstaller.dll is located.
9. Run the following command to create the EventSource:

   InstallUtil EventLogSourceInstaller.dll
