You're asking in the wrong place; the webpage can be confusing

You're asking in the wrong place; the Microsoft webpage can be confusing and
may have misled you. This is a technical support newsgroup for Microsoft
Access databases - we are all volunteers here, not Microsoft employees, and we
do not have any influence over licensing or product keys.

Contact whoever sold you the Microsoft program (whichever of Microsoft's many,
many  programs that was) and verify that it is in fact a legal copy.
