Requested resource in use Exception - Orchestrator

I am getting “Requested recource is in use” exception everytime I connect my bot with Orchestrator. Below is full log:

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

Hi @shailesh_gohel

Usually appears when you use High-Density Robots (server machine with multiple users) and you have the logintoconsole parameter set to true in the UiPath.settings file.

Do you have the robot on a windows server machine?


Hello @ovi,

I am getting the same error. Using UiPath Community addition and trying to run the Job on

Robot is created on Windows 10 machine and successfully deployed. Tried with logintoconsole parameter as “True” & “False”.

Have you also tried on Just to be sure.

Yes, I have tried on both and

Getting same error on both.

I don’t see any other option but how about this.
Just stop UiRobot service (all by the same name if available ) from service manager and restart the Service and give a try.

Hello @ddpadil,

Also tried that option. Stopped UiRobot Service and checked after restarting it. Still the same behavior.

I also tried Manual and Scheduled execution with Robot Type = Free.


Try the following:

The error usually appears:

  • hd robots
  • machine is overloaded
  • rdp is not enabled
  • another user use the session

Let me know your findings.



One and simple solution that you need to login your orchestrator with your PC/Laptop’s admin user name and password

Hi Andrei,
If i disconnect the machine before starting a job, it is working. What would be the solution for this?
I noticed that, when the first bot completes the run from orchestrator, it is not logging off and we are getting “request is in use” when i run the second bot.

I manually tried to login with second bot’s credentials and i got the below message.

I am getting the same error when ever i try connecting to orchestrator. I dont use any remote machine to connect. I have the uipath process in a machine and i connect the robot from the same machine via I tried even using platform/ but same error persists. I even changed loginToConsole tp false. Yet no solution. Can some one please help me?
Thanks in advance.

Hi Sravenco,

Have you tried all the solutions provided by Andrei above?

yes. i tried.

You can also get that error if you are using Launch Workflow Interactive with Logontoconsole checked.

Only other time I’ve seen this is when:

  • Logontoconsole is set to true on the server it’s being run on
  • Server is set for only 2 users max and a 3rd user tried to run a job while 2 are connected

I am getting the same error when ever i try run the robot using orchestrator. I have Win10 and the latest version of UI Path. And i tried all solutions higher. Help me please!


We had this issue and the problem was that the password contained special characters (in Turkish). We solved it by creating a new user with the password containing English characters.
I hope this solves your problem.


thanks for answer!
We solved this problem similarly

as per the discussion i had with UiPath support team there was a mistake on their website regarding this Logontoconsol which need to be false. soon same will be updated on robot guide.

Hi Adrei,

I manage my demo account with UiPath.

My robot installed like this below.

I’m using one machine. Windows10. I installed the studio in my machine. And i connect platform.uipath with same machine.
When i work from below, it works correctly
and sends to orchestretor succesfull maessage.

But when the time comes to trigger from it gives an error below.

I controlled my remote desktop connection setting, and i saw that it gives permission. By the way it is company computer, if there is any extra point i can give details.

My Machine : TR01BUTN1208
Robot name: hakan
