About UiPath Remote Runtime
UiPath Remote Runtime is a component which facilitates the communication between a remote application or desktop, such as Citrix Virtual Apps, and the dedicated UiPath extension – the UiPath Extension for Citrix, the UiPath Extension for Windows Remote Desktop and Apps, or the UiPath Extension for VMware Horizon. It gathers info about targeted UI elements of remote applications and sends them to the corresponding extension, so that selectors are natively generated in UIExplorer.
Starting with Citrix Virtual Apps and Desktops 7 2109, all custom virtual channels are blocked by default. This prevents the UiPath Remote Runtime from working correctly.
To solve this issue the UiPath virtual channel must be added to the allow list policy:
UIPCTX,C:\Program Files (x86)\UiPath\RemoteRuntime\UiPathRemoteRuntime.exe
The Remote Runtime component was granted a Citrix Ready certification, making it a trusted, effective solution for working with Citrix technologies.
Depending on the type of environment you want to build your automation projects on, the UiPath Remote Runtime component can be installed as follows:
- On Citrix Application servers – communicates with the UiPath Extension for Citrix.
- On VMware Horizon servers – communicates with the UiPath Extension for VMware Horizon.
- On Windows Remote Desktop machines – communicates with the UiPath Extension for Windows Remote Desktop and Apps.
The corresponding UiPath extensions must be installed on the client machine.
The UiPathRemoteRuntime.msi
installer can be downloaded from:
- Product Downloads in the UiPath Customer Portal
- Resource Center in the UiPath Automation Cloud. To access Resource Center, log in to your Automation Cloud Organization and click the Help button on the navigation bar.
Once the UiPath Remote Runtime component is installed, it registers a task in the
Task Scheduler so that the UiPathRemoteRuntime.exe
process
is started at every user login, for every user logged in to the remote server.
The UiPath Remote Runtime component is required to establish the connection between an application or desktop server and a corresponding UiPath extension installed on a client machine. This way, selectors are natively generated on the client machine where Studio is installed, without having to rely on OCR and image recognition activities.
Hardware and software requirements
The UiPath Remote Runtime has the same requirements as the UiPath Robot. See the full list of requirements in Hardware and Software Requirements.
Installing the UiPath Remote Runtime
From the Installer
- Run the
UiPathRemoteRuntime.msi
file to install the UiPath Remote Runtime. It needs to be installed on all the Citrix Application servers, VMware Horizon servers, or the Windows Remote Desktop machines on which you want to create your automation projects. - Log off from the current Citrix window, VMware Horizon window, or RDP session on the client machine and log back in. This is required so that your changes take effect.
- Install either the UiPath Extension for Citrix, UiPath Extension for VMware Horizon, or the UiPath Extension for Windows Remote Desktop and Apps on the client machine, depending on the technology on which you want to create your automation projects.
You can also choose to deploy the extension for Java, Chrome, Microsoft Edge, Firefox, Microsoft Remote Desktop and Apps, VMware, and Citrix from the installer, as well as the Task Scheduler entry, by selecting the corresponding options, as depicted below:
UiPathRemoteRuntime.msi
installer and choose the corresponding
option.
From the Command Prompt
- Click the Windows Start button and type
cmd
in the search field. - Right click on Command Prompt and run it as administrator.
- Change the directory to the
UiPathRemoteRuntime.msi
folder (for example:cd C:\Tools\Studio
). - Use the
UiPathRemoteRuntime.msi ADDLOCAL=RemoteRuntime,RemoteRuntimeTask
command to install the UiPath Remote Runtime component. - Log off from the current Citrix window, VMware Horizon window, or RDP session on the client machine and log back in. This is required so that your changes take effect.
- Install either the UiPath Extension for Citrix, UiPath Extension for VMware Horizon, or the UiPath Extension for Windows Remote Desktop and Apps on the client machine, depending on the technology on which you want to create your automation projects.
Additionally, you can use the following options to install extensions:
UiPathRemoteRuntime.msi ADDLOCAL=RemoteRuntime,RemoteRuntimeTask,JavaBridge,ChromeExtension,EdgeChromium,CitrixClient,FirefoxExtension,WindowsRdpExtension,VMwareExtension
– installs the Remote Runtime component, the Task Scheduler entry, the extension for Java, the extension for Chrome, the extension for Microsoft Edge, the extension for Citrix, the extension for Firefox, the extension for Microsoft Remote Desktop and Apps, and the extension for VMware Horizon.
You can also perform a silent installation by using the /quiet
parameter:
UiPathRemoteRuntime.msi ADDLOCAL=RemoteRuntime,RemoteRuntimeTask /quiet
- silently installs the Remote Runtime component and the Task Scheduler entry.
You can install the UiPath Remote Runtime at any location using the APPLICATIONFOLDER
option:
UiPathRemoteRuntime.msi APPLICATIONFOLDER="D:\UiPathRemoteRuntime" ADDLOCAL=RemoteRuntime,RemoteRuntimeTask /quiet
– silently installs the Remote Runtime component inD:\UiPathRemoteRuntime
, and adds the Task Scheduler entry.
You can now create processes to automate on Citrix Virtual Apps and Desktops, VMware Apps, as well as over RDP connections just as you would on a standard machine. Because of the corresponding extensions, OCR and Image recognition activities are no longer required to properly identify UI elements. Instead, elements are natively recognized and can be used with any activity.
Task Scheduler
By default, the UiPath Remote Runtime component creates an entry in Windows Task
Scheduler to automatically start every time the corresponding user logs in. This feature
is represented by the Create Launch UiPathRemoteRuntime task option in the
UiPathRemoteRuntime.msi
installer, which you can choose to disable,
if necessary.
The Remote Runtime Task Scheduler entry can be added or removed via the installer
or the Command Prompt, as explained in the following sections. If the entry is removed,
you must launch the UiPathRemoteRuntime.exe
process using another
method, like a startup script.
Adding Remote Runtime dependencies
Interactive selection on the target application does not build correct selectors unless the UiPath.UIAutomation.Activities matches the UiPath Remote Runtime dependency on the Citrix Application server, VMware server, or the Remote Desktop machine.
For example, if you want to build an automation project using the UiPath.UIAutomation.Activities package version 21.10.7, you also need to copy the corresponding UiPath dependency from the client machine (where Studio is installed) on the Citrix Application server, VMware server, or the Remote Desktop machine.
This is done as follows:
- On the client machine (where Studio is installed), navigate to the
%UserProfile%\.nuget\packages\uipath
folder. All installed UiPath dependencies are located here. - Copy the version which corresponds to the UiPath.UIAutomation.Activities package you want to use. You can view the list of dependencies shipped with the UiPath.UIAutomation.Activities package on the About UIAutomation Activities page or by checking the package dependencies in Studio > Manage Packages.
- On the Citrix Application server, VMware server, or the Remote Desktop machine, navigate to the
%ProgramFiles(x86)%\UiPath\RemoteRuntime\packages\uipath
folder and paste the previously copied UiPath dependency version here.
Selectors are now properly generated with your current version of the UiPath.UIAutomation.Activities. Changes take effect as soon as the dependency is copied.
The Remote Runtime Dependencies described above are required both for the design time and execution time.
UIAutomation dependency
The UiPath Remote Runtime has a dependency on the version of the UiPath.UIAutomation.Activities package, not on the version of UiPath Studio/Robot.
The Remote Runtime installed on a remote machine must have the version of the latest UIAutomation package you want to use in your projects, and it is compatible with the previous UIAutomation releases (it is backwards compatible).
The UiPath.UIAutomation.Activities package and the UiPath Remote Runtime have the same UiPath driver dependency. For each UIAutomation package released version, a download link for the UiPath Remote Runtime component with the same version number is provided.
You can download the UiPathRemoteRuntime.msi
installer from:
- Product Downloads in the UiPath Customer Portal.
- Resource Center in the UiPath Automation Cloud. To access the Resource Center, you need to log in your Automation Cloud Organization, click the Help button on the toolbar and choose Resources > Downloads.
- Or you can request it through the Contact Technical Support page.
Side-by-side support
The UiPath Remote Runtime component is installed on the Citrix Application server, VMware server, or Remote Desktop machine in the %ProgramFiles(x86)\UiPath
folder. All installed versions are visible in the %ProgramFiles(x86)%\UiPath\RemoteRuntime\packages\uipath
folder.
When you build or execute a process, you need to use a UiPath.UIAutomation.Activities package which is compatible with the deployed driver version of the UiPath Remote Runtime.
The version of the UiPath driver dependency for the UiPath.UIAutomation.Activities package is displayed in Studio, in the Project Dependencies section.
The same UiPath version must be present on the remote machine, in the %ProgramFiles(x86)%\UiPath\RemoteRuntime\packages\uipath
folder.
UiPathRemoteRuntime.msi
installer contains the latest UiPath
dependency, as well as the latest supported Long Term Support (LTS) UiPath
dependencies.
The table below enlists the dependencies between the UiPath.UIAutomation.Activities package and UiPath Remote Runtime:

You can verify the Remote Runtime build number from the UiPathRemoteRuntime.msi
file Properties, in the Details tab, in the Comments field.
If you use a version of the UiPath.UIAutomation.Activities package that has a UiPath dependency which is not part of the set of installed UiPath dependencies on the remote machine, selectors are not generated and the following exception is thrown: The UiPath.UIAutomation.Activities package is incompatible with the UiPath Remote Runtime running on the server.
Remote Runtime architecture
When you start a process, the Robot sends out the necessary commands to the extension for Citrix or Windows Remote Desktop via an RPC channel. This information package also contains details about the version of the UIAutomation package used to build the process.
The corresponding extension then forwards the information package via an ICA virtual channel to the UiPath Remote Runtime component, which is on the Citrix Application servers or Remote Desktop machine.
Depending on the version of the UIAutomation package with which the process was built, the UiPath Remote Runtime component instructs the Robot Executor which driver to use.
Multiple ICA channels
Communication between the Remote Runtime Component and the corresponding extension is done via an internally-developed ICA channel. Multiple ICA channels can be used, but the Citrix Receiver, for instance, already uses several channels for the clipboard, audio, and more.
Data transfer and bandwidth considerations
Once the Remote Runtime component is installed, you can create your automation projects without having to create any firewall rules.
Data transfer between the Remote Runtime and extension requires little bandwidth usage. For example, each action the Robot performs (such as a Click activity) transfers around 3 KB of data.
Multiple remote connections
If you jump through multiple remote connections (RDP, Citrix, or VMware) to reach a destination remote computer, where the automation is developed, you must install Remote Runtime on each intermediary remote computer, not just on the target one.
Consider the following scenario: Machine A (with Robot) connects through RDP (or Citrix, or VMware) to Machine B, and from Machine B another connection is opened to Machine C, where the automation must be performed. In this example, the following configuration is required:gm
-
Machine A – install RDP extension.
-
Machine B – install RDP extension and
RemoteRuntime.msi
. -
Machine C – install
RemoteRuntime.msi
.
