# Installing Nexthink VDI Client Extension

Nexthink VDI Client Extension is a lightweight agent for personal employee devices and self-managed endpoint devices connected to virtual desktop environments (VDIs). The extension sends only relevant data to the Nexthink instance from devices on which Nexthink Collector cannot be installed.

{% hint style="info" %}
[Nexthink VDI Client Extension](#download-the-extension) is included as a component in Nexthink Collector; therefore you do not need to install it separately on company-managed devices accessing virtual environments.

For **company-managed devices**, see the [installing-collector-on-windows](https://docs.nexthink.com/platform/configuring_nexthink/bringing-data-into-your-nexthink-instance/deploying-nexthink-in-non-vdi-environment/installing-collector/installing-collector-on-windows "mention") documentation to learn how to install Collector.

### Platform compatibility

Nexthink VDI Client Extension supports Citrix, Microsoft Azure Virtual Desktop (AVD) and Windows 365 Cloud PC (CPC), and can be installed on endpoints running Microsoft Windows.

## Download the extension

Download the VDI Client Extension MSI file directly from Nexthink on the [Collector management](https://docs.nexthink.com/platform/user-guide/administration/system-configuration/collector-management) dashboard under **Administration > Collector management > Downloads**.

## Install the extension

Choose between the following installation paths:

* **Manual**, which highlights all steps during the process
* **Silent**, which runs without user intervention

### Manual installation

Run the MSI file like any other executable to launch the VDI Client Extension installer, and follow the steps. This starts the installation process with Windows Installer.

### Silent installation

Run the following command in a command-line interface (CLI) to install the extension without user interactions; replace `<VERSION>` with the version of the extension:

```powershell
msiexec /i NEXThink_VDI_Client_Extension_<VERSION>.x86_64.msi /qn
```

## Connect to a VDI session

Once the installation is complete, you are ready to reconnect to your VDI session, and Nexthink can start complementing the remote session information with relevant metrics from the client device.
