Hi UiPath,
Need guidance in connecting my machine to UiPath orchestrator.
I can’t connect it using a machine key please see details below:
Did someone experience this situation?
Please let me know
thanks in advance 
can you try running the UiPath studio as administrator?
Also, make sure you are connecting using correct parameters.
Else, use Interactive sign-in. You need to enable to from cloud orchestrator and then just simply sign-in.
I assume that you have registered your Robot as a service. In order to modify the service’s configuration you must be an administrator.
This applies to Machine Keys, Logging Level, etc.
If you do not wish to have this constraint, Studio / Robot should be installed in User Mode which is installed in the Users Profile and requires the User to manually launch the UiPath Assistant / UiRobot process.
