Why can't I activate Microsoft Office on Galaxy Book?

So I have uninstalled the Microsoft Office Professional Plus from my computer (where license was activated there), my computer has restarted. Then I connected my laptop to the internet and tried to activate the office license by logging in with my account. Unfortunately that did not work. Is it because my laptop has Office 2019 Home or 365 version? Do I have to install Office Professional Plus there?

Usually you will get a message telling you to install ProPlus.

Unfortunately, you have to load it via a special file / program that is actually intended for companies only. A link should be included with your key.

Note that the conclusions, especially if you have purchased them cheaply on the Internet and are a private person, are often blocked. Then you have to buy a new key for a few €, which in turn will run until reinstallation.

Of course, if the key belongs to Prof. +, it will NOT work with a Home.

You already have to install the corresponding version on your laptop…

Since you've got me worried because I bought the key about Mmogga

Buy a new one there that runs i.d.R. Until the next new installation or hardware change.
