I am upgrading my machine with a new MOBO and SSD. I need a full windows 8.1 install disk so I am trying to create one from the WindowsSetupBox.exe file.
I am doing this on the machine that I will be upgrading and it currently has 8.1 Pro. When I enter my product key (yes confirmed correct) I get 'This product key didn't work. Check it and try again.'
My MOBO is coming today and I really want to get this thing done tonight but I can't even begin without an 8.1 Pro install disk. any help is much appreciated.
NOTE: I tried the regedit fix that I found for the same error on activating windows. (no luck)
