Running UIRobot from task scheduler with “Run whether user is logged in or not” is not working

Hello,

I have create a simple batch file that calls UIRobot.exe for the purpose of automation testing. It runs fine when I schedule it in Task Scheduler on a Windows Server, with the setting “Run whether user is logged in”f. However, since I am trying to run even when the user is not logged on, when I check this setting to "Run whether user is logged in” and “Run High priority”.

Please help me on this to resolve the issue ASAP .

Thanks,
