How to resolve this cmd.exe exception?

I am trying to start a task from the task scheduler. The task will basically run a 'runas /savecred /user:abc job.bat' to start a process. However it has failed. I find this error message in event log and I think it can be relevant.

If I run runas /savecred /user:abc job.bat directly in a DOS prompt, it works without issue.

The reason I cannot run it as abc directly is because it use MS Office COM object. When it tries to open a powerpoint filem it will throw this exception:

Error HRESULT E_FAIL has been returned from a call to a COM component

Is there way to make it work?
