Silent installation

Install UiPath Robot 2026.10 without prompts, using the UiPath Platform Installer from the command line and a platformConfig.json file.

A silent installation runs the UiPath Platform Installer from the command line with no prompts. Use it to script an installation, or to deploy the Robot to many machines. A configuration file, platformConfig.json, selects the Robot and sets its parameters. The UiPath Platform Installer, distributed as an MSI package named UiPathPlatformLTS.26.10.msi, replaces the UiPathRobot.msi and UiPathStudio.msi installers, which don't ship for 2026.10.

For more details about the Platform Installer, refer to Install the desktop clients and Update channels.

Install the Robot silently

1. Create a platformConfig.json file that requests the Robot package and sets its parameters. For an example, refer to Robot parameters.

2. Open an elevated command prompt. A silent installation runs per-machine only when the command prompt is elevated, and service mode needs a per-machine installation.

3. Run the installer with the configuration file:

   msiexec /i UiPathPlatformLTS.26.10.msi PLATFORM_CONFIGURATION_FILE="C:\Config\platformConfig.json" /qn
   

   The LTS installer sets the channel itself, so you don't pass a channel.

To install silently with the offline installer, refer to Offline installer. To deploy the Robot with Configuration Manager (SCCM) or Intune, refer to Deploy with Configuration Manager or Intune.

The Robot is installed without prompts. Connecting at install time with a client ID and secret works only for a per-machine installation with the Unattended robot type (REGISTER_ROBOT_SERVICE set to "true"). SERVICE_URL, ORCHESTRATOR_CLIENT_ID, and ORCHESTRATOR_CLIENT_SECRET are all required, and the installer skips the connection if any is missing. The connection is best effort: after installing, check that the robot is connected in Assistant or on the Machines page in Orchestrator. If it isn't, connect the Robot to Orchestrator after the installation.

For every installer parameter and the format of both configuration files, refer to Install from the command line.

The PROXY_* installer parameters of earlier versions don't exist for the Platform Installer. To install behind a proxy, put the proxy settings in an updater configuration file and add UPDATER_CONFIGURATION_FILE="C:\Config\updaterConfig.json" to the msiexec command line. For the file format, refer to Install from the command line. For the proxy the Robot itself uses, refer to Redirecting robots through a proxy server.

Robot parameters

The Robot's parameters are set in the Robot entry of platformConfig.json. Parameter values are strings, and on/off parameters take "true" or "false".

The following example installs an unattended robot in service mode, connects it to Orchestrator with client credentials, and installs the browser extensions, which are a separate package:

{
  "Packages": [
    {
      "PackageName": "Robot",
      "InstallRequested": true,
      "Parameters": {
        "REGISTER_ROBOT_SERVICE": "true",
        "SERVICE_URL": "https://cloud.uipath.com/<Organization_Name>/<Tenant_Name>/orchestrator_",
        "ORCHESTRATOR_CLIENT_ID": "<Client_ID>",
        "ORCHESTRATOR_CLIENT_SECRET": "<your-client-secret>",
        "INSTALL_LIVE_STREAMING": "true"
      }
    },
    {
      "PackageName": "BrowserExtensions",
      "InstallRequested": true,
      "Parameters": {
        "INSTALL_CHROME_EXTENSION": "true",
        "INSTALL_EDGE_EXTENSION": "true"
      }
    }
  ]
}

Assistant is a separate package that depends on the Robot, and the Robot installs without it. For attended use, request the Assistant package next to the Robot package, as in the following example of an attended robot in user mode:

{
  "Packages": [
    {
      "PackageName": "Robot",
      "InstallRequested": true,
      "Parameters": {
        "REGISTER_ROBOT_SERVICE": "false"
      }
    },
    {
      "PackageName": "Assistant",
      "InstallRequested": true,
      "Parameters": {}
    }
  ]
}

The Robot package accepts the following parameters:

Parameter	Description
REGISTER_ROBOT_SERVICE	"true" registers the Robot Windows service, so the Robot runs in service mode. Per-machine installations only. A per-user installation ignores it.
SERVICE_URL	The Orchestrator URL. Required with ORCHESTRATOR_CLIENT_ID and ORCHESTRATOR_CLIENT_SECRET, with ORCHESTRATOR_AUTO_SIGNIN, and with ENFORCE_DEFAULT_SERVICE_URL.
ORCHESTRATOR_CLIENT_ID	The client ID of the machine template or standard machine. Set it together with ORCHESTRATOR_CLIENT_SECRET. Only with REGISTER_ROBOT_SERVICE set to "true": the installer rejects client credentials otherwise, including in a per-user installation. A per-user robot never runs in service mode, so use ORCHESTRATOR_AUTO_SIGNIN or sign in from Assistant instead. Can't be used with ORCHESTRATOR_AUTO_SIGNIN.
ORCHESTRATOR_CLIENT_SECRET	The client secret that goes with ORCHESTRATOR_CLIENT_ID.
ORCHESTRATOR_AUTO_SIGNIN	"true" signs attended users in to SERVICE_URL automatically. Can't be used with REGISTER_ROBOT_SERVICE set to "true".
ENFORCE_DEFAULT_SERVICE_URL	"true" enforces SERVICE_URL as the Orchestrator URL for all users of a user mode robot.
LICENSE_KEY	A Robot license code to activate on the machine without Orchestrator.
PACKAGES_FOLDER	The folder the Robot downloads process packages to.
NUGET_OPTIONS	DisableOnlineFeeds stops the Robot from using the online activity feeds. The default is EnableOnlineFeeds.
CUSTOM_NUGET_FEEDS	Additional package feeds, in the form Name1,Source1;Name2,Source2.
INSTALL_ROBOTJS	"true" installs RobotJS. On a first silent installation, a per-user installation or a per-machine installation without the Robot service installs it even if you leave it out.
INSTALL_LIVE_STREAMING	"true" installs the RealVNC components used for live streaming and remote control. Off unless you set it.
ASSISTANT_STARTUP	"true" starts UiPath Assistant when the user signs in to Windows.
DISABLE_SECURE_XAML	"true" turns off XAML protection for Windows - Legacy projects.
ENFORCE_SIGNED_EXECUTION	"true" runs only signed packages.

Telemetry isn't a Robot parameter. To turn it off, add the Platform Installer property TELEMETRY_ENABLED=0 to the msiexec command line.
