In Acrobat X Pro, I have created a blank digital signature block. When I try to enable reader rights (File > Save As > Reader Extended PDF > Enable Additional Features) I get an error message saying "This document could not be reader enabled".
The document has 4 text fields that the Reader user will be able to fill in. I created them by adding text boxs. None of them are read only.
The document also has the blank signature block. I created that by creating a new form field, choosing the digital signature, and drawing the box where I want the signature.
I've checked the security settings, and nothing is not allowed.
I just need this to be opened in Reader, and have someone digitally sign it. The digital signature works when I click on it in Acrobat. I am just unable to enable reader rights. What else can I do?
