Hello again,
Finally, I found out what was wrong.
Problem was with tasks made in task scheduler on remote machine, all of them are V2 compability.
What I did was recreating those tasks with V1 compability (Create New Task -> in first tab for combobox 'Configure for' choose option 'Windows Server 2003, Windows XP, or Windows 2000').
Discusion from this topic https://taskscheduler.codeplex.com/discussions/405210 helped me with locating my mistake.
Hope those information will be usefull for somebody.
Greetings
