Criar New source no eventviwer windows c# .net

[alfinete]

bom dia

no c# estão a criar uma entrada no event viewer do windows 10

mas eu quero criar um novo source


se não criar novo source corre bem e insere
____________________________________________________________

       /// <summary>
        ///
        /// </summary>
        /// <param name="IsError"></param>
        /// <param name="MsgError"></param>
        public static void SaveEventViewer(bool IsError, string MsgError,string  InfoSource, string LogName)
        {

            using (EventLog eventLog = new EventLog("Application"))
            {
              
                eventLog.Source = "Application";
                eventLog.WriteEntry(MsgError, !IsError ? EventLogEntryType.Information : EventLogEntryType.Error, 101, 1);
            }
        }

se puser a criar novo source esta a dar o seguinte erro

public static void AddMessageToEventLog(string MsgError, EventType type,string InfoSource, int id)
        {
            try
            {
                EventLog elog = new EventLog("");

                if (!EventLog.SourceExists(InfoSource))
                {
                    EventLog.CreateEventSource(InfoSource, "Application");
                }

                elog.Source = InfoSource;
                elog.EnableRaisingEvents = true;
                EventLogEntryType entryType = EventLogEntryType.Error;

                switch (type)
                {
                    case EventType.ERROR:
                        entryType = EventLogEntryType.Error;
                        break;
                    case EventType.INFORMATION:
                        entryType = EventLogEntryType.Information;
                        break;
                    case EventType.WARNING:
                        entryType = EventLogEntryType.Warning;
                        break;
                }
                elog.WriteEntry(MsgError, entryType, id);
            }
            catch (System.Security.SecurityException secError)
            {
                // If the user don't have administrator rights a SecurityException will be
                // thrown if the source didn't exist.
                // You need to handle this...
            }
            catch (Exception eventError)
            {
                // Catch other exceptions that can happen when you try to write to
                // the event log...
            }
        }

The source was not found, but some or all event logs could not be searched. Inaccessible logs: Security.​
