High-density feature not working



Testing High-desity feature by triggering from rest api through script with 2 different users, but showing following error:

Executor start process failed, reason System.Runtime.InteropServices.COMException (0x800700AA): The requested resource is in use

Some addition settings:

Studio/Robot/Orchestrator Version: 2017.1.6434

OS Version: Windows Server 2016 Datacenter ( Microsoft Azure )

Access can be granted to this server in test environment, if interested ones wants to troubleshoot.

Thanks in advance





Not sure if it helps, but check to which location your license file is pointed in Uipath settings file.

This was in 2016.2.

This didn’t work, used to get “Robot already in Use” pop up message.


This worked



Hi vvaidya

Could be that the 2017 version of uipath studio is looking for license somewhere, which triggers this issue when more than 1 session is using uipath service. However, regarding UiPath it is Orchestrator that controls this. I am only triggering workflows through rest API.

Best regards
