Hello Tom,
This issue is not related to Windows for Business or Windows 365 Enterprise; it is strictly a Windows Server 2022 Remote Desktop Services licensing problem. The wizard defaults to “License Pack (Retail Purchase)” because the license server was activated using the Web Browser method, which often restricts available license program options. To install Select Plus CALs, the license server must first be properly activated through the Remote Desktop Licensing Manager using the “Automatic connection” method. Once the server is activated correctly, the Install Licenses Wizard will allow you to choose “Select” and enter the license pack ID from VLSC. If the option still does not appear, it usually means the CALs were issued under the wrong program type, and you’ll need to escalate with your licensing provider or Microsoft Volume Licensing support to have them corrected.
I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!
Harry.
