Hi niatross and welcome to our community!
If you are referring to anything "Legal" wise with regards to
what you produce using Captivate, there is nothing you have to do
as far as Adobe is concerned. They supply you the software and you
are totally free to do what you want with the output from that
software.
However, you could run up against a possible legal issue if
perhaps you used Captivate to record something that was copyrighted
and distributed that.
Make sense? I hope so.
Cheers... Rick
