Help! Can't run any processes

Hi guys, I am trying to learn how to use UIPath as a part of a uni course, but have been greeted with a significant obstacle. If I try to run anything I get this:

19.1.0+Branch.master.Sha.3db2bfe8751ed76c2c21f7ee16f53ff69a3e3b75

There was no endpoint listening at net.pipe://localhost/UiPath/service/duplex/agent/rd10s that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at net.pipe://localhost/UiPath/service/duplex/agent/rd10s that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

I have checked to see if net.pipe listener is running and it is. I have re-started the service, re-installed Uipath. Nothing seems to work. I need this to work or I’l actually fail this module. Please help.

Thanks & Regards

What is the UiPath version you have installed in your machine?

@Madhavi - I think @Rahul_Datta is using UiPath version 19.1.0 as it appears from the log.

@Rahul_Datta - Did you install Orchestrator on your local machine?

Nope, do I need to?

Pardon my cluelessness.

@Rahul_Datta - No, you do not need to install Orchestrator on your local machine. I was trying to narrow down the issue.

Can you please check the below post and the solution suggested by @Lavinia? Hope this helps.

@Rahul_Datta Can you go to Control panel and check is there two instances(different versions) of UiPath installed?

Okay I did a complete re- installation after deleting the folders from Roaming and Local in %appdata%. Before that I went to Windows features and enabled all the features under .Net after which I could see the net.pipe listener service running which was previously missing. This appears to have resolved the issue. I would like to sincerely thank everyone for their assistance and support. This really is a fantastic community :slight_smile:
