I can't add additional signatures to my document. I have read all of the threads and tried the solutions but none work. I am using Adobe Acrobat Pro 8 and have a document that requires a signature from the author and two approving signatures. I save the word document as a PDF then click certify with visible signature. I place the signature and sign, selecting "form fill in and digital signatures" under permitted changes after certifying. I then save the document and send it to the first approving official. When he clicks on the sign menu all options none of the options work except "validate all signatures" and "getting started with digital signatures" he has pro version 8 as well. Any thoughts
I do not think this can be done in version 8. You need version 9 or higher.
If the Version 9 does not work for you, you could enlist a third-party digital signature provider to drag and drop signature fields into your PDFs and even create templates.
SIGNiX is a good option.
