My new device has been repaired at the acer shop and a reset was done. This inactivates the programs. Office, which I unlocked before the reparation has been gone.
Because I already used the key for office 2019 home & student once I cannot install it again on the same device. I tried for over two hours with the Microsoft assistant but it does not work. I'm also confused, because sometimes the reply from the system is,
that I have no abonnement, but office 2019 is no abo.
Do I have do deinstall? reinstall or just reactivate?
Does anyone know what I have to do step by step?
