# Unable to assign a license to a Hyper-V host

## Issue

> You have the license but cannot assign it to your **Hyper-V** host.

***

## Resolution

To assign the correct installer license for **Hyper-V** hosts, you must use a dedicated **Hyper-V per socket license**. This license type is based on the number of processor sockets in the physical machine.
