Getting taskKill Error in workflow execution

Hi,

I am running simple workflow for opening the GUI of automationedge from WEB GUI through process studio.
Getting the following error:

Hi Shital,

It is not exactly clear from your question, what exactly are you trying to achieve through the workflow. Do Elaborate a bit please. Are you simply trying to open the AutomationEdge Web GUI or you are trying something else? And are you getting this error at Exit Browser stage?
