Windows SPLA Licence

Hello
After adding my SPLA licence it confirms me that i have succeyyfully added it but in Manage my Licences shows "NO RESULT" and Operating System(OS) Shows>> "There is no operating system installed on your server" . I get blocked and cannot process further.

Would you pls confirm my Lincence so i can go for further process. Thank you

Hello,
After adding the license, you should be able to install a Windows Server OS on your server. Can you please check if this works?
