Installing 2022 RDS licenses in a MS Server 2019 Server

Hello,

To install the Remote Desktop Services 2022 licenses on your Server, you can follow these steps:

1. Sign into the server you want to use as the license server using an administrator account.
2. In Server Manager, select Manage > Add Roles and Features.
3. On the Select installation type page, select Role-based or feature-based installation.
4. Specify the server on which you’ll install the licensing role.
5. On the Server Roles page, check the box for Remote Desktop Services, then select Next until you see the Remote Desktop Services page.
6. Select the roles you want to install. Make sure you include the Remote Desktop Licensing role.
7. In the Add Roles and Features Wizard dialog box, select Add Features. Select Next until you see the Confirmation page, then select Install.
8. Once the RD licensing role is installed, open the Remote Desktop Licensing Manager.
9. Right-click the license server, and then click Install licenses.
10. Click Next on the welcome page. Select the program you purchased your RDS CALs from, and then click Next.
11. Enter the information for your license program. In most cases, this will be the license code or an agreement number, but this varies depending on the license program you’re using.
12. Click Next. Select the product version, license type, and number of licenses for your environment, and then click Next.
13. The license manager contacts the Microsoft Clearinghouse to validate and retrieve your licenses.
