Unable to run FME workbench with Python setup on Task scheduler. It runs fine when I run manually. It gives 0x1 error.

Hi @hima​ 

It could be related to an issue with PYTHONHOME environment variable.

Do you have this environment variable?

Can you confirm what is your workspace PythonCompatability setting?

Are you running the Task via your own user or a service account?

There is a Q&A about this issue which may help.
