This scenario is for a Client Access License (CAL). Purchases for a Client Access License (CAL) are not for a software product but rather for a license that gives a user the right to access the services of the server. In this case, a software download file is not required to activate a CAL. Instead, the product is activated and installed through the product’s activation wizard. 


  1. Go to https://admin.microsoft.com and type your global admin credential under the Billing menu, then click on Your products.

  2. Choose your type of license purchased.


  3. After selecting your license, click on Show activation keys.


  4. Copy your key.


  5. Log in to the Windows Server and follow the steps below. Launch Licmgr.exe from the server where the RDLS role is installed.


  6. Select the machine name from the left tree view control. Right-click on the server name, then select Install Licenses.


  7. Click Next.


  8. Select the option for Retail CAL installation denoted as License Pack (Retail Purchase) from the License Program drop-down list, then click Next.


  9. Paste the key that you have copied before.


  10. Click Finish.


  11. You should see your license installed.
