@bestseo Had the same problem in the past. Fixed it by manually starting "C:\Users\User\AppData\Local\TaskScheduler\1.6.0\Scheduler.exe" before starting the Scheduler GUI ("C:\Users\Phoenix\AppData\Local\TaskScheduler\1.6.0\gui\SchedulerGui.exe") and executing all with admin-rights.
So these projects work for a few days, and then problems appear, right?
Please attach a test project with which you can repeat the problem, here or in the forum PM.
