I have created 3 packages.   Each package has the following settings.

Run on a schedule.  Run at System Startup
Run as soon as possible after scheduled time
Run with the Local System Account
Run whether a user is logged in or not
User Input Required (yes, it is checked)
Remove this task after successful install (yes, it is checked)

I have a Sequential Task that will install all 3 packages.  This Task has the following settings.
Run on a schedule.  Run at System Startup
Only run at scheduled time

I have a test collection that I target.  The job runs and the machines get all 3 packages.   When I reboot the packages run at start up.

But...... the 3 tasks remain in the Altiris Agent Software Delivery display window even though "Remove this task after successful install" is checked.  So the next time the machine reboots the 3 packages all run again, which we of course don't want.  I have tried playing around with the schedule too trying different options and nothing seems to work. 

I do not see a "Remove this task after successful install" check box on the Sequential Task page for some reason.

So my question is how do I run a sequential task at system startup and have the 3 called packages only run once and never again?

Thank you.
