The UiPath Installation and Upgrade Guide

Updating the Robot

Before you proceed with updating the Robot, we highly recommend checking out the compatibility matrix.

It is usually recommended to first upgrade your Orchestrator and then your Robots.

🚧

Important:

After an Orchestrator update, the Robots have to be reconnected to Orchestrator in order for them to apply the new settings.

Regardless of the version you want to update from, you need to take into consideration how the Robot was installed, in Service Mode or in User Mode.

As a general rule, we advise you to have the same Robot, Studio, and Orchestrator, so that you can take advantage of all the latest features. Studio and Robot must have the same version. You can always check the Robot version from the Assistant or from Orchestrator.

The installation artifacts are provided when you first purchase Robot or they can be provided by your customer success manager or our support team.

📘

Note:

If both Studio and Robot are on the same machine, you have to upgrade them at the same time, regardless if the Robot was installed in Service Mode or in User Mode.

To update the Robot, run the UiPathStudio.msi installer using the installation wizard or from the command line. UiPathPlatformInstaller.exe is no longer available starting with version 2021.4.

Prior to version 2021.4, Studio and Robot were available as 32-bit applications. Starting with version 2021.4, a 64-bit installer is available by default. A 32-bit version is also available and can only be installed on 32-bit operating systems.

Update existing UiPathStudio.msi and UiPathPlatformInstaller.exe Enterprise installations as follows:

  • Use the 64-bit version of the installer (UiPathStudio.msi) to update existing installations on 64-bit operating systems.
  • Use the 32-bit version of the installer (UiPathStudio-x86.msi) to update existing installations on 32-bit operating systems.

Existing installations on 64-bit operating systems that are using the default installation path (C:\Program Files (x86)\UiPath\Studio) are migrated to C:\Program Files\UiPath\Studio after updating with the 64-bit installer. If the older version is installed in a custom location, the update does not change the installation path.

📘

Important:

Remember to properly migrate your processes when updating the 2018.3 UiPath Platform. The dependencies and activities installation algorithm has improved, which can cause conflicts when executing processes with packages installed from local feeds. If you encounter any issues while updating, check out possible solutions on this page. Also, remember to check out how to Open Projects Created with Previous Versions.

Service Mode Robot

If the Robot was previously installed in Service Mode and you want to update it, running UiPathStudio.msi without changing any settings in the installation wizard automatically replaces all the old files without modifying any of your settings.

Please keep in mind that, upon upgrade, the activities packages are cumulated in the C:\Program Files\UiPath\Studio\Packages folder. Find out more about managing dependencies.

To update the Service Mode Robot from the command line, use the following command: UiPathStudio.msi ADDLOCAL=DesktopFeature,Robot,RegisterService.

User Mode Robot

Enterprise Edition

If the Robot was previously installed in User Mode and you want to update it, running UiPathStudio.msi without changing any settings in the installation wizard automatically replaces all the old files without modifying any of your settings.

To update the User Mode Robot from the command line use the following command: UiPathStudio.msi ADDLOCAL=DesktopFeature,Robot

📘

Note:

It’s important to know that if you had the UiPath Studio and Robot running on 32 bit on an Operating System running on 64 bits, you can only update using with the 64 bit UiPathStudio.msi installer.

Community Edition

If the Robot was previously installed with the Community installer (UiPathStudioSetup.exe), it is automatically updated to the latest version on the selected channel - Stable or Beta. For more information, see Updating the Community Edition.

Please note that the Robot’s connection to Orchestrator is lost if you close Studio while the Community Edition automatic update is running. This issue does not reproduce on UiPathStudioSetup.exe installations that are licensed.

Robot Deployment Conversion

When updating the Robot, you can also switch it from Service Mode to User Mode, or vice versa. This is only possible when using the UiPathStudio.msi installer.

📘

Note:

When converting the Robot from Service-Mode to User-Mode, the Robot might not be able to access the .xaml files from original NuGet Packages folder. For details on how to resolve this, please read this guide which offers more details on this specific scenario

📘

Note:

When updating the configuration variables, the Robot has to be restarted for changes to take effect. However, when updating the following settings in Orchestrator, a restart is not needed:

  • RunDisconnectedHours
  • SignalR settings (including on/off)
  • HeartbeatPeriodSeconds
  • NuGet feeds
