I purchased LiveCycle Designer ES4 on February 5, 2018. I am finding the PDF file generated from LC cannot be used well by my target audience using Adobe Reader. The users cannot save a electronic copy of the file. It would appear the solution offered by Adobe would be to obtain license for Reader Extensions, however, I am unable to find a means to accomplish that seemingly simple task.
I need help in obtaining Reader Extensions for Adobe LiveCycle ES4.
Unfortunately the image did come through. Anyway, this would tell me that the 'Save as other' didn't save or get set to ‘Enable More Tools (Including form fill-in and save)…’. Once the form is saved in Acrobat Pro with this setting selected, the form should function just as it does under Pro.
Not sure you can make the box itself dynamic to allow for expansion, however you can make the contents wrap and expand by using the 'Allow Multiple Lines' in the field properties for the box you want too expand. You may want to try the Expand to fit on the layout page as this points to an anchor point and the starting location.
As for allowing the form to be fillable in reader, if you have Acrobat Pro, you can:
From the File menu
Select ‘Save as Other…’
Select ‘Reader Extended PDF’
Select ‘Enable More Tools (Including form fill-in and save)…’
Then save the form again. Prior to using the form, the user will be required to enable Java, but they have to do this to even see the form.
What software is the user using. If it is Adobe Acrobat Reader, and the form was built in LiveCycle Designer, you need to access the form in Acrobat Pro and change it. Here is a link on how to do this.
