Problem running workflows with Task Schedule in Windows Server 2008 R2 Standard

Hi everyone,
I installed OpenRPA in a PC with Windows Server 2008 R2 Standard. Then I create a new task in Task Schedule to run one of my workflows every day. Task Schedule open OpenRPA but don't run the workflow and shows this message in logging box:
[Error] System.Exception: 360, 143, 1200, 750 is not a valid value for Int32. ---> System.FormatException: Input string was not in a correct format.

If I execute the command in cmd, powershell or in a .bat file, I have the same error.

Also I try to Enable Child Sessions, but the RPA throw me this message:

If I run the workflow pressing the run button, the workflow runs correctly

Thank you in advance

No, you cannot do RPA from a service or a scheduled task that is not running in the users context. That is what HD robots are for ( or child sessions, but you cannot use those )

Did you even read the message ? it clearly states your windows version is not supported for child session. Only Windows 8/server 12 and above is supported.

@allan-zimmermann thanks for the answer, the problems with Child Session are solved.

Now my unique problem is when I open and run one workflow with powershell, I tried with administrador mode too, the command open the program but don't run the workflow.

If I run the workflow pressing the run button, the workflow runs correctly.

Run it how ? show the command you used.
If you don't share what you did, you a basicly just saying "it does not work" and all I can reply is, "yes it does" ... Not helping either of us ...

NEVER run the robot as administrator ( or powershell for that matter ) if something requires you to run something as admin, be spectical.
