How do I activate an Office 365 annual subscription?

I bought a laptop (Medion AKOYA E4254). This laptop includes Microsoft Office 365 Personal with a one-year subscription. My question is, how do I activate this now… I signed in, but still needs to activate my account. (See the screenshot)

If I click on activate now, I have to enter a product key that I do not have… How do I get that or do I need the skin? (See the screenshot)

You could look around https://support.office.com/de-de/article/aktivieren-von-office-5bd38f38-db92-448b-a982-ad170b1e187e!

Yes, that does not get me any further, since I have exactly the problem: I can't find a product key!

A product key is necessary.

This should be included with the PC.

Often the product keys for Windows and possibly also for xl are on the bottom of the laptop or under the battery (if removable).

Otherwise go to the dealer and ask for it (possibly also by phone)

Did you even try pressing Enter? Sometimes it works, but rather I suspect that Office was activated as bait only for a short time.

In the meantime, you can edit your files with Libre Office (download for free without any activation). Handling and Feeling are slightly different, in principle very similar and also similar in the program capabilities (some +, some -, VBA macros sometimes go now, but not yet reliable, LO "understands" other languages, such as Python VBA macros edit / write works, but without help, and then you quickly come up against limits Macros in VBA recording is my knowledge -not? - not)

LO can also save edited files as .xls, .xlsx, .xlsm, and other formats.

Have just read again: is the first activation, so not expired. Good, try the above. (Supplement to papers?)

There's a 16-digit code under the laptop, but an Office 365 product key must have 20 letters / numbers.

Sorry, meant under the laptop is a 20 digit code and I need a 25 digit.
