Our VP of Sales insists he cannot sign a PDF in Acrobat Standard DC which was created in an older version, such as Standard 9, and wants to continue using Standard 9 (he had this previously on his old PC, and says he could use it to sign these types of PDFs). I actually don't have Acrobat Standard DC installed on my machine, so can't play around with it to find out if this is true. Is there a compatibility setting he is missing?
Thanks in advance!
