Sorry, I'm using Windows 10 Pro. No error, it actually tells me that activation was successful with product key blah blah blah. Going into to settings I'm not activated, even after a reboot. Trying the program again nets the same results same product key listed.
thanks for feedback.. i'll add the solution to the app in the next build

(the solution was tested by me and i have an activated windows 10 pro)
by the way, same product key:
yes it's the same, it works on any windows 10 of any machine but it
needs an add-on then you will have a life-time activated windows 10 with a secure activator
the missing
3rd PARTY add-on in v1.0-Build1 is the problem, so i'll add it in the next build
