I am trying to legally activate Acrobat X. Can I purchase a S/N anywhere?

I am trying to use US government websites that require Acrobat X or less.  I have the Acrobat X .exe, but need a legal serial number.  How do I get one?

Paying for a subscription? I don't know any other legal way.

Adobe doesn't sell this version any more. However, that requirement is probably wrong. Try to open the file with a newer version and it should work.
