Refer to the log for complete error details.

How can i fix this? I create an environment variable called hostname and try to set hostname in the .bat, but the error occurs again.

If you are using it in .bat file, are you having it as HOSTNAME or %HOSTNAME% ?

In .bat i tried

SET HOSTNAME=%COMPUTERNAME%
