is it possible to start a program from a job, the jobs ends but the exe runs until it is killed by task manager?
Thomas is right. You'd have to launch the process using something else (VBS, C#, etc..) as a task, that starts a process and then quits, but the process remains. There's no native support for 'fire and forget' process execution currently in VisualCron that I've ever seen. I think this might be a good option for a Feature request. On the Process--Execute task maybe add a check box that, when checked, does NOT wait for output and just executes and moves to the next task (or quits job, if no other tasks, following standard flow).
