1). I am having Desktop Agent error(Registration Failed) and also I am attaching the screenshot for your clarification.
2). I am unable to find the 'IRPA Service-trail' Intelligent Robotic Automation in service market place of trail version to register the service key. As i am thinking this could be one of the reason for failing to connect the desktop agent.
3) I have also configured the roles and also maintained hierarchy in the cloud factory.
