@Fox I tried this code but my problem was not solved.
I guess there is no solution.
Try downloading and using "Scheduler" as a separate application. You can download it from your Bablosoft personal account page.
@Moderator didnt help :(

@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.
