After a clean Install of Windows 11 Pro, and second thing, Windows Updates done, received licence code in seconds, entered the key, it worked directly, done, I get Retail activation (Again with SharewareOnSale) as expected.
No need for Vocal or SMS Phone activation this time. (Previously happened and I hate when it happens with Microsoft products, as I pay to get it want it simple, no hassle)
So it works wonderfully!
Thanks
