thanks for your response .
Unfortunatly each time I tried to open a ticket on microsoft support site, they're asking for contract or subscription . and I cannot access to step 2 (Probleme description) without adding contract or subscription. I have neither. just bought media and licence to a reseller for one of my customer.
I really don't have any clue yo how open support ticket without charges.
and also I'm unable to see how open a ticket under “Product Activation” for Windows Server.
no way to continue without adding support ticket
