New-ScheduledTaskAction : The term 'New-ScheduledTaskAction' is not recognized as the name of a cmdlet

Question

My script is like-

$action = New-ScheduledTaskAction -Execute "BolusDemoDataGenerator.BAT"
$TaskStartTime = [datetime]::Now.AddMinutes(2) 
$trigger = New-ScheduledTaskTrigger -At $TaskStartTime -Once

$setting = New-ScheduledTaskSettingSet
$inputTask = -action $action  -trigger $trigger -settings
Register-ScheduledTask BatchRunTask -InputObject $inputTask

but I am getting an error

recognized as the name of a cmdlet, function,
script file, or operable program. Check the spelling of the name, or if a

With PowerShell 4.0 a scheduled task can be easily created with the new cmdlets New-ScheduledTaskAction, New-ScheduledTaskTrigger and Register-ScheduledTask, but unfortunately it's not possible in the prévious versions (have a look to PSVersion in $PSVersionTable).

For previous version you can find many examples where people invoke the schtasks.exe command.

If you want to avoid calling external executables and do as much in PowerShell as possible you can use the Task Scheduler’s com object for creating a scheduled task.

# Open the Task Scheduler com object
$service = new-object -ComObject("Schedule.Service")
