# RAS Guest Agent installation options

To be managed in a Remote PC pool, a Remote PC must have RAS Guest Agent installed. This can be done using one of the following options:

* When you add an individual Remote PC to a pool, you'll be asked to upgrade the agent. Follow the onscreen instructions and install or upgrade it.
* When you add all Remote PCs in a host to a pool at once, you can add them first and then use the **Tasks** > **Upgrade all Agents** menu option in the **Desktops** tab.
* When you assign Remote PCs to a Provider via Active Directory, you can have a Group Policy in the OU with a script to deploy the agent. See [**Configuring the Provider** > **Dynamic (VDI subtype)**](/landing/ras-admin-guide/parallels-ras-21-administrators-guide/virtual-desktop-infrastructure-vdi/remote-pc-pools-in-vdi/adding-remote-pcs-to-a-provider.md).
* To install or upgrade the agent on an individual Remote PC, select it in the **Desktops** tab and click **Tasks** > **Troubleshooting** > **Check agent** option. In the dialog that opens, click **Install**.
* Finally, you can install RAS Guest Agent manually by running the Parallels RAS installer on a Remote PC and selecting to install the RAS Guest Agent component.
