So I have a server running Windows Server 2012 that I want to upgrade from the evaluation version, to full. Going through the process of using Powershell to find the current and target editions, and then applying
DISM /online /Set-Edition:<edition ID> /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXX /AcceptEula,
to update, I continually get the error that my product key is wrong. I am not quite sure why this is happening because I did indeed buy the correct key. Any ideas as to what is wrong?
