Access Denied when initiating task by windows task scheduler in windows 10

I have implemented a COM Action handler for windows task scheduler. Everything works fine in windows 7 but in windows 10 we get error 0x80070005 (Access Denied).

I don't know which permission is missed?

Note: this situation is observed only in S4U mode.

My Task definition is as follows:

Thanks in advance for your comments.
