# Hyper-V environment is not visible in XMS despite installing the agent on the host

## Issue

> You cannot see your **Hyper-V** environment in **Xopero ONE Management Service** (**XMS**) even after installing the agent on the host.

***

## Resolution

Remember to use the appropriate installer to natively secure the **Hyper-V** host for external backup. This dedicated installer can be downloaded from the [**XMS**](#user-content-fn-1)[^1] in **Virtual Machines** > **Hyper-V** tab using the **(+) Add new** button.

{% hint style="danger" %}
If the **Hyper-V** host was added as a regular agent (with endpoint or server license), go to the **Devices** tab, select the device, and choose **Delete** from the top menu (<mark style="color:$danger;">**without deleting data**</mark>). With the correct installer and a **Hyper-V** per socket license, the license will be assigned automatically.
{% endhint %}
