When you run syntax from command prompt you've to wait 7 seconds until confirmation popups appears (7 seconds after insalling cert and other 7 seconds after inserting key with SLMGR.VBS -ipk command). You also need to run command promt as admin.
Yep, I did. I got first and second messages -"successfully". And I started cmd as admin. But activation doesn't work - product key is invalid. And when I typed slmgr -rearm just 15 days left
Thanks for trying my suggestions. IMO FC module. Anyway I´ll try to figure it out and do a working mod since Wonder Woman´s I´ve done shows slic already. Yen
