Lots of sites show how to use it, but they leave some key things out. I am attempting to use it with Windows 10 64-bit. So, first off, this is what you see when you open the program:
??? work in progress
0 or 0x0: The operation completed successfully.
1 or 0x1: Incorrect function called or unknown function called. (did you use the correct start in folder and/or environment path for the bat/exe?)
2 or 0x2: File not found.
10 or 0xa: The environment is incorrect.
0x41300: Task is ready to run at its next scheduled time.
0x41301: Task is currently running.
0x41302: Task is disabled.
0x41303: Task has not yet run.
0x41304: There are no more runs scheduled for this task.
0x41306: Task is terminated.
0x8004130F: Credentials became corrupted (*)
0x8004131F: An instance of this task is already running.
0x80070002: Basically something like file not available (2147942402)
0x8007010B: Action ‘start in’ directory can not be found.
0x800704DD: The service is not available (is ‘Run only when an user is logged on’ checked?)
0xC000013A: The application terminated as a result of a CTRL+C.
0xC06D007E: Unknown software exception.
