going from 7 ultimate to 10 pro it was,the old 1511_1 iso worked both loaded from tech bench thanks for the reply's guys
You wanted to upgrade from 7 Ultimate you have to use an iso containg at least 10 Pro, Singlelanguage is Home/Core only.
i ran their free upgrade once,now i can install clean win10 on my system and it self activates while connected to the web. click the "i dont have a product key" on install
