How to update studio


My studio is currently at 2018.1.4, and I’d like to update it to 2018.4.1. I have download the latest one, while 2018.1.4 still in my computer. When I want to run the robot in 2018.4.1 studio, it reports an error"could not connect to uipath robot"
In the same time, I am unable to type settings in the 2018.4.1robot.
How can I do?

Thanks in advance!


Hello chen1,

It seems that the robot is not running on your machine, can you make sure if it is started. Please follow the below steps to start the robot on MS Windows machine:
Go to Start menu then select “UI path Robot” and click on it. It will start the robot service.

The error message indicates what you need to check.
It sounds like you installed UiPath using the two different installer packages (MSI and EXE). You can tell as
UiPath Studio is found in two locations depending on the installation package you initially used.

If you used the MSI package it is installed per machine by users with administration rights and can be found in:


If you use the exe package “User Mode Installation” UiPath Studio is in the local AppData directory for the user running the installer, which does not require administrator rights.


And you will find a child directory (e.g. app-18.4.1 ) based on the version you have installed.

More information can be found in their online documentation:

I would suggest:

  1. Uninstalling the older version, and ensuring the UiRobot service is started for the newer one.
  2. If you have two UiRobot services and would like to keep the older one for some reason, stop the older one and ensure the new version is running.

To check the services

  1. Open Services from your Windows Start Menu
  2. Find UiPath Robot in the Services list
  3. Ensure the Service is started, if not ClickStart the service

Alternatively, you can run it from the command line. Run Command prompt as administrator (or select Yes to the UAC when prompted.

"%PROGRAMFILES(X86)%\UiPath\Studio\UiRobot.exe" --restart
