UiPath Orchestrator - Permission missing: Remote Execution

Hi Marina,

This error is displayed when you are trying to run a process on a Robot without a license or with a Front Office license.

Check this post for Usual Orchestrator errors: Usual Orchestrator errors (FAQ) - Troubleshooting

If you have Orchestrator 2017.1 and the Robot has Attended license(Front Office), it wouldn’t appear anymore on Robots list in Start Job modal.
But if you have the 2016.2 version, please check if the Robot you are trying to Start the job on has Front Office license.
