# Configure a multi-hop connection

> To reach a destination remote computer via multiple connections, you must install Remote Runtime on each intermediary remote computer, not only on the final target computer.

To reach a destination remote computer via multiple connections, you must install Remote Runtime on each intermediary remote computer, not only on the final target computer.

## Scenario: RDP connections

Consider the following scenario:

* Machine A (with Studio and/or Robot) connects via RDP (Microsoft Remote Desktop Protocol) to Machine B, and
* Machine B connects via RDP to Machine C, where the target application is running, and the automation must be performed.

In this example, the following configuration is required:

1. Machine A – install Studio/Robot and the **Extension for Microsoft Remote Desktop and Apps** (UiPath RDP extension).
2. Machine B – install the **Extension for Microsoft Remote Desktop and Apps** and `UiPathRemoteRuntime.msi`.
3. Machine C – install `UiPathRemoteRuntime.msi`.

If other types of connections are used between two machines, you must configure a connection at each hop, with the appropriate extension:

* **Extension for Citrix** for the case of Citrix connection
* **Extension for Microsoft Remote Desktop and Apps** (UiPath RDP extension) for the case of RDP connection
* **Extension for VMWare Horizon** for the case of VMWare connection

## Scenario: RDP connection and Citrix connection

Let's consider another scenario in which:

* Machine A (with Studio and/or Robot) connects via RDP to Machine B, and
* Machine B connects via Citrix to Machine C, where the target application is running, and the automation must be performed.

On Machine B (or other intermediary machines), you can install the extension with one of these methods:

* Run the `UiPathRemoteRuntime.msi` installer and select from the **Product Features** list the required extension. Refer to [Installing the UiPath Remote Runtime - From the Installer](https://docs.uipath.com/studio/standalone/2024.4/user-guide/about-uipath-remote-runtime#from-the-installer).
* From Command Prompt run `SetupExtensions.exe` (located in the folder `C:\Program Files (x86)\UiPath\RemoteRuntime`) with the parameter corresponding to the required extension:

## Automating Java or web applications

Regardless of your multi-hop connection scenario, if you are automating a Java application or a web application, you must also install the corresponding extension (the extension for Java, Chrome, Microsoft Edge, Firefox) on the remote machine. This can be done by running:

* the `UiPathRemoteRuntime.msi` installer, as described in [Installing the UiPath Remote Runtime](https://docs.uipath.com/studio/standalone/2024.4/user-guide/about-uipath-remote-runtime#installing-the-uipath-remote-runtime), or
* the `SetupExtensions.exe` tool located in the installation folder of **UiPath Remote Runtime** (default `%ProgramFiles(x86)\UiPath\RemoteRuntime`), as described in [About the SetupExtensions tool](https://docs.uipath.com/studio/standalone/2023.10/user-guide/about-the-setupextensions-tool).
