Can't start job from Orchestrator with unattended robot

Hi everyone,

I’m trying to start a job with an unattended robot from orchestrator. This is the error I’m getting:

Could not start executor. The requested resource is in use. (Exception from HRESULT: 0x800700AA)

The robot is set to use windows credentials and I have tried running the job with and without a password.

When starting the job from UiPath assistant it works fine.

Hope someone can help, thanks in advance.

When you have Studio open it takes your account instance. So you can not run unattended on the same account.

Either run unattended via Assitant (Studio closed so your account is free) or Run the unattended bot on another account instance on Windows Server.

Windows Server OS example:

  • UiPath Studio (or any Robot) > yourMachineName/robotAccount1
  • UiPath Unattended Robot > yourMachineName/robotAccount2

All in al: you can not run 2 robot licenses on the same account.
PS: Windows 8/10 don’t have simultaneous logins so you need WindowsServer OS

Thank you very much for your help, I will give it a try.
