Hi @Abudhahir - please open your local services and check if the service “UiPath Robot” is running as shown in the picture below:

Hi all,

I have actually the same issue, but the UiPath Robot shows “running” in the services table. I have the latest version 2019.4.2.

Does anyone has a solution?

Thanks for helping! :slight_smile:

Best regards

And thats the error message:

System.Exception: Could not connect to UiPath Robot Service. Make sure the service is started!
at UiPath.Models.UiPathDuplexProxy.FaultTolerantProxy.g__CheckService|10_0()

Make sure if Older versions exists and maybe causing conflict with New version. Verify Admin Privilegies too. Uninstall and reinstall latest, reboot and try again.

Hi asesor-rpa,

thanks for your quick reply - but it did not work.

What else could it be? Is there any option to install an older version maybe? 'Cause with all older version, everthing went well.

Best regards

Disable antivirus and check events log viewer to see what happens when service starts. Stop and Start manually from services panel

Hi Asesor-rpa,

unfortunately, I am not able to stop it manually.

Does the screenshot help?

Best regards

Solution: Sounds strange but did work: I took an older link to download an older version of UiPath software. Somehow, they transformed the link so I got the latest version anyway.

BUT: Then it worked - maybe it will help. Just take another link in case you have my descripted issues.

Thanks to all of you anyways :slight_smile:

Best regards

Could also be licensing issue if expired.

I too faced the same issue when trying to run simple programs on UiPath 2019.9.2. I also had older version of UiPath Studion 2018.4 on same machine. After trying all the permutations and combinations, when i uninstalled 2018 completely … the code on 2019.9.2 ran.

I believe that newer versions of UiPath cannot co-exist with older versions.

@Abudhahir Please check task manager and make sure UiPath.Service.Host.exe is running along with your UiPath.Agent.exe.

Good morning,

I have face the problem “Could not connect to uipath robot service, make sure the service is started”.

I already have done the stop and start in Services location but it didn’t work. I need some help!

Thank you,

hey @Pedro_Alves ,
I too faced the same issue.

Just uninstall the UiPath studio and reinstall it. Try running the same project again. you’ll get the output for sure.

I did this and worked for me. :slight_smile:

Thank you.

Also you can try restarting the system.
when i reinstalled the uipath it was working fine. And when i opened the UiPath after shutting down the pc, that same issue came .

Then i just restarted the system. error gone.

Just try this way guys.


I am having the same issue

I am currently trying to activate my licence key from the free trial
First off he didn’t recognize my orchestrator url, since it got moved into the cloud recently I thought it may have something to do with that.

The real issue that is similar to the one you gave is the fact that when I open my assistant it tells me that UiPath robot service is not recognized. Yet it is running. And when I force restart it, or stop then start it again, it seems to never recognize it.

That may also have something to do with the fact that I did the 60 days trial, but since I did, I uninstalled UiPath and reinstalled it.
Please help.

Hi @Corentin_Caspers

You mentioned that you are using the trial key, but also that you are using the Cloud Orchestrator.
Therefore, could you clarify:

  • do you want to switch to the Community Edition after using the Trial Enterprise edition before?

If so, the best way would be to clear all your UiPath files and start fresh:
How to fix your Studio installation / Licensing issues

Now, if you are trying to go the other way, from Community Edition to the Enterprise trial, you might want to check if the key you got is not for the Orchestrator, rather than for just Studio. If that is the case, you will have to install Orchestrator on-premise and then connect your robots to it to get the licenses.

You can verify your situation at this contact form to our licensing support:

Thank you about the information.

I did succeed in accessing it, but with a recent update or many for some reason after updates of my machine, UiPath stopped recognizing it…

I will try clearing all my files and see if this changes anything.
