# Command Line Parameters

> Install Studio from the command line with the UiPath Platform Installer, using msiexec parameters and a configuration file that selects the desktop clients.

You can install Studio and the other UiPath desktop clients from the command line by running the UiPath Platform Installer with `msiexec`, either interactively or silently. Silent mode is intended for unattended deployments to multiple machines.

## Syntax

```
msiexec /i UiPathPlatformLTS.26.10.msi [PARAMETER=value ...] [/qn]
```

Pass parameters as `PARAMETER=value` pairs after the package path, and enclose values that contain spaces in double quotes.

* Omit `/qn` to run the installation wizard with its full user interface.
* Add `/qn` to run without a user interface. Partial-UI modes, such as `/qb` and `/qr`, are not supported for unattended installations.

The installer runs per-machine when `msiexec` runs elevated, from an elevated command prompt or as `SYSTEM` from a deployment tool. A silent installation started from a non-elevated prompt installs per-user, without an error. To make a per-machine installation explicit, pass `MSIINSTALLPERUSER=0`. For details, refer to [Installation scope](https://docs.uipath.com/uipath-platform-installer/standalone/latest/user-guide/install-from-the-command-line#installation-scope).

## Installer parameters

| Parameter | Description |
| --- | --- |
| `FORCE_PERUSER` | Set to `1` to install per user, even when an administrator runs the installer. |
| `MSIINSTALLPERUSER` | Set to `0` to make a per-machine installation explicit. The installation must still run elevated. |
| `PLATFORM_CONFIGURATION_FILE` | The absolute path to a configuration file that selects the desktop clients to install and their options. For details, refer to [The configuration file](#the-configuration-file). |
| `UPDATER_CONFIGURATION_FILE` | The absolute path to a configuration file for the updater, used for proxy settings. |
| `TELEMETRY_ENABLED` | Set to `0` to turn off usage data collection, or to `1` to keep it on. Telemetry is on by default. |
| `INSTALLER_LANGUAGE` | The language of the installation wizard, such as `en`, `de`, `fr`, `ja`, or `pt-BR`. It has no effect in silent mode. |

`UiPathPlatformLTS.26.10.msi` sets the Enterprise LTS (26.10 line) [update channel](https://docs.uipath.com/uipath-platform-installer/standalone/latest/admin-guide/update-channels) itself, so you don't pass `CHANNEL`.

For the full list of values and for the proxy settings, refer to [Install from the command line](https://docs.uipath.com/uipath-platform-installer/standalone/latest/user-guide/install-from-the-command-line).

## The configuration file

The file passed in `PLATFORM_CONFIGURATION_FILE` lists the desktop clients to install, each with its own parameters:

```json
{
  "Packages": [
    {
      "PackageName": "Studio",
      "InstallRequested": true,
      "Parameters": {
        "INSTALL_STUDIO_LEGACY": "true",
        "INSTALL_ACTIVITIES": "true"
      }
    },
    {
      "PackageName": "Robot",
      "InstallRequested": true,
      "Parameters": {
        "SERVICE_URL": "https://orchestrator.example.com/organization/tenant/orchestrator_"
      }
    },
    {
      "PackageName": "Assistant",
      "InstallRequested": true,
      "Parameters": {}
    },
    {
      "PackageName": "Runtimes",
      "InstallRequested": true,
      "Parameters": {}
    },
    {
      "PackageName": "BrowserExtensions",
      "InstallRequested": true,
      "Parameters": {
        "INSTALL_CHROME_EXTENSION": "true",
        "INSTALL_EDGE_EXTENSION": "true"
      }
    }
  ]
}
```

Keep the following in mind when you write the file:

* `PackageName` values are case sensitive: `Studio`, `Robot`, `Assistant`, `Runtimes`, and `BrowserExtensions`.
* List every desktop client to install. A client that is missing from the file is not installed, including `Assistant`, which the installation wizard selects together with Studio.
* Studio requires `Robot` and `Runtimes`, and `Assistant` requires `Robot`. A missing required package is not added, and the installation fails validation.
* Write every parameter value as a string, including `"true"` and `"false"`.
* If `Parameters` is empty for `BrowserExtensions`, no browser extension is installed on a machine that doesn't have one.
