Unusual error trying to run

studio

Hi guys, I need some help here - I have just just installed UIPath Community, and get this error whenever I try to run:

16:40:21:904 => [ERROR] [UiPath.Workflow.Logging.StudioTraceListener] [38] System.AggregateException: One or more errors occurred. ---> System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at net.pipe://localhost/UiPath/service/duplex/agent/Lucas that could accept the message.

Can you go to Event Viewer -> Windows Logs -> Applications and let us know if there is any log with UiPath Source?
Is UiPath Robot Tray opened? Can you open Settings from it?

Hi Lavinia,

Thanks for your help with this. There is no log in Event Viewer -> Windows
Logs -> Applications with UiPath Source, and there is no UI Path robot tray
visible or running.

It really seems like something has gone wrong with the install. Note that I
had a 60 day trial version that I installed and removed back in early 2016

  • would this be causing problems with UIPath community or the install?

I also had some trouble with the Community install initially which seemed
to be due to McAfee anti-virus running. But I stopped it and it seemed to
install ok?

Do you have a script that will do a complete uninstall (rather than the
windows uninstall) of all trial / community editions - I have no automation
files/projects that I need to keep? Or should I try to install the trial
edition instead of the Community edition since its a package rather than an
.exe (which may be more Windows 10 friendly)?

Thanks, Lucas

We do not have a script for a full uninstall but let’s check to see if there are some leftovers from the previous installation:

  1. In Windows services is there any UiRobot/UiPath Robot service? If yes, disable it and restart the machine.
  2. Where UiPath was installed are there any files left? (usually in C:\Program Files\UiPath folder)? If yes, remove them manually.
  3. Delete any %localappdata%\UiPath, %programData%\UiPath folder.

As a last resort, yes, you can try installing the trial edition and let us know if this works. You might need a trial extension that you can request from the website.

Cheers,
Lavinia

I also got same error and solved another way.

try stop process C:\Program Files (x86)\Dropbox\DropboxOEM\DropboxOEM.exe if you run.
