Problem with activation after reinstallation

[Vertolla]

I recently reinstalled the system on my laptop, along with Microsoft Office. Now, when starting Word and Excel, a message appears that the program is not activated. I tried to enter the old key, but it does not work. It is expensive to buy a new key for me now. Maybe someone faced a similar problem

I had a very similar situation when I reinstalled the system on my laptop and reinstalled Microsoft Office with it. Then I started looking for alternative solutions and was recommended to use the kms activator office 2021. This is a tool that allows you to activate Office without having to buy a new key. After that, Office worked in full, without any restrictions.
