"You cannot save data typed into this form" !

Thank you, Tony!

It worked in Adobe Acrobat DC Pro''.  I don't know why they are implying above the end-user has to do the extended save in Pro.  I did it and forwarded the resulting PDF and it works perfectly.

Thanks!

Not the end user, but the person who is distributing the form to the end users. That Acrobat license allows the licensee to Reader-enable documents and distribute them, but it does not allow the licensee to sell Reader-enabled forms to someone else who distributes them.

As you said above, George, "You can't use Reader, you have to use Acrobat. So your client will have to get Acrobat and Reader-enable the forms that you develop. If you don't have Acrobat, you can download and install the trial version so you can test this out." 

The key words being, " . . . So your client will have to get Acrobat and Reader-enable the forms that you develop."  It was just a tad misleading, which is what I was commenting on to Tony.  And, downloading a trial version?  My clients do not have installation rights, much less the desire to install Acrobat DC Pro.  All they want is a working form for their Adobe Reader DC.

'Not "selling the form either, by the way."  Sorry.

Thank you for your input.  It is none the less appreciated.

Tony had the correct answer.  The end-user DOES NOT have to have Acrobat DC.  The form must be made "Reader enabled," but that can be done by the author prior to distribution.  Follow Tony's steps and you'll be good.
