I have a server that I am trying to install Server 2019 Standard. The Volume Licensing activation key is not working. The product was downloaded from the Volume Licensing portal along with the license key. The activation pane shows a product ID, and on the product key space the last (5) digits are already populated.
Open Command Prompt
slmgr /ipk #####-#####-#####-#####-#####
slmgr /ato
c:\windows\system32\slmgr.vbs /ipk PRODUCT_KEY
hit ENTER
Sample: c:\windows\system32\slmgr.vbs /ipk 12345-12345-12345-12345-12345
slmgr.vbs -ipk YOUR PRODUCT KEY.
