When Preview is selected inside Task Scheduler an error is returned:
'System Error. Code 1722'
'The RPC Server is unavailable.'
This is resolved by starting the 'Print Spooler' service.
Additionally, to get the preview within Task Scheduler, a print driver must also be installed.
Package can be run once scheduled manually, though the service is installed and running.
1. Click File -> Options -> Execution
