I have installed an Acrobat Pro DC and found that I cannot sign a pdf document with a digital ID stored in the computer.
In Acrobat Pro XI, there is a prompt ask me to mark the place for the signature and then I need to enter password to sign the pdf document.
Now in Acrobat Pro DC, I can sign a pdf document with either "initial" or "signature" and both do not required the input of password.
Following the on-line instruction, I have prepared an ID stored in my computer and have create a personalized signature.
Your kind advice to solve this problem will be greatly appreciated.
p.s. My OS is Windows 8.1 Enterprise English 64-bit
