Issues Signing PDF

Issue/Question

I am unable to sign a form that a student electronically signed as well. When I click on the signature field where I am supposed to sign the field blinks and does nothing. I am able to fill out non-signature fields in this same form as well.

Environment

• Adobe Acrobat Reader

Cause

Adobe Acrobat Reader does not have the correct Certificates installed or the previous signer of the PDF form signed the form using something other than Adobe Acrobat Reader or Adobe Pro to sign the PDF.
