Actual Question:

Many times, I receive a form from a client that can be filled out with Adobe Acrobat. Sometimes there is no field for date or some particular field was forgotten. When I try and edit the form, or add text for a date - I get the following error window: "This form cannot be edited in Adobe Acrobat DC. Please use Adobe LiveCycle Designer to edit this form." I have the Creative Cloud style Adobe suite. There is no LiveCycle Designer in that suite. Info: Designer ES4 comprehensive design tool | Adobe LiveCycle Enterprise Suite 4

What exactly is going on? Am I really not able to add a string of text to a form with Acrobat Pro? - or has this document been built with a legacy product / and that is the real problem?

Any ideas or help to make Acrobat a useful tool would be wonderful, otherwise - I'll just go back to printing these forms and sending them in the mail. Thanks.

If using the digitally sign feature of Acrobat/Reader, there is a special digital certificate that is attached to the PDF that includes a lot of information as when the PDF form was signed and information to tell if the form has been changed and the ability to "roll back" the form to a state prior to the signature being applied.

Fill and sign is a different product for applying a signature to the PDF.

Use of the digital certificate can be used to validate legal or business forms internationally and comply the legal signature standards that have been internationally agree upon. "Fill and sign"  has no such standing or ability, so any formed signed by the "Fill and Sign" option should not be recognized as legally binding in an U.S. court or the courts in many other countries. You might find a court that accepts the "Fill and Sign" but that ruling can easily be overturned because of its lack of conformity to international standards and the standard in the U.S. established by the UCC.
