我有一个WiX安装程序,我在其中使用以下自定义操作在任务计划程序中创建几个任务。

[CustomAction]
        public static ActionResult CreateScheduleTaskForUpdateTriggering(Session session)
        {
            session.Log("Creating the Scheduled Task");
            string MyAppPath = Environment.GetEnvironmentVariable("MyAppPATH");
            if (!IsTaskExisting("MyAppUpdateTrigger"))
            {
                session.Log("Command Created : " + "C:\\Windows\\System32\\SCHTASKS.exe /Create /TN \"MyAppUpdateTrigger\" /SC ONCE /TR \"" + Path.Combine(new string[] { MyAppPath, "Watchdog", "RunMyAppInstaller.bat" }) + "\" /RL HIGHEST");
                Process p = Process.Start("C:\\Windows\\System32\\SCHTASKS.exe", " /Create /TN \"MyAppUpdateTrigger\" /SC ONCE /TR \"" + Path.Combine(new string[] { MyAppPath, "Watchdog", "RunMyAppInstaller.bat" }) + "\" /ST 00:00:00 /SD 01/01/1990 /RL HIGHEST");
            }
            else
            {
                session.Log("MyAppUpdateTrigger schedule already exists");
            }
            return ActionResult.Success;
        }

        [CustomAction]
        public static ActionResult CreateScheduleTaskForRunningWatchdog(Session session)
        {
            session.Log("Creating the Scheduled Task for running watch dog");

            string MyAppPath = Environment.GetEnvironmentVariable("MyAppPATH");

            if (!IsTaskExisting("RunWatchDog"))
            {
                session.Log("Command Created : " + "C:\\Windows\\System32\\SCHTASKS.exe /Create /TN \"RunWatchDog\" /SC ONSTART /TR \"" + Path.Combine(new string[] { MyAppPath, "Watchdog", "RunWatchDog.bat" }) + "\" /RL HIGHEST");
                Process p = Process.Start("C:\\Windows\\System32\\SCHTASKS.exe", " /Create /TN \"RunWatchDog\" /SC ONSTART /TR \"" + Path.Combine(new string[] { MyAppPath, "Watchdog", "RunWatchDog.bat" }) + "\" /ST 00:00:00 /SD 01/01/1990 /RL HIGHEST");
            }
            return ActionResult.Success;
        }

我在下面的WiX文件中调用它们。

<CustomAction Id="CA_scheduleTaskAction" BinaryKey="removeFolderCustomActionDLL" DllEntry="CreateScheduleTaskForUpdateTriggering" Execute="commit" Return="ignore" />
<CustomAction Id="CA_scheduleTaskActionForWatchDog" BinaryKey="removeFolderCustomActionDLL" DllEntry="CreateScheduleTaskForRunningWatchdog" Execute="commit" Return="ignore" />

<InstallExecuteSequence>
  <!--Custom Action="LaunchWatchdog" After="InstallFinalize" /-->
  <Custom Action="WatchDog.TaskKill" Before="InstallValidate"/>
  <Custom Action="CA_scheduleTaskAction" After="InstallFiles"/>
  <Custom Action="CA_scheduleTaskAction" After="InstallFiles"/>
  <Custom Action="CA_myCustomAction" Before="InstallFinalize">Installed</Custom>
</InstallExecuteSequence>

虽然创建了第一个计划任务,但任务计划程序中缺少第二个计划任务。日志确实表明自定义操作已运行。但它并不存在于任务调度程序中。当我手动运行命令时,它会被创建。我在这做错了什么?任何帮助将非常感激。以下是日志。
