When setting up an electronic signature, the window "You don't have a digital certificate for this signed document" appears.

If you have created a digital ID card before, and it can only be used to sign the currently opened PDF file; When signing another PDF file, the "You don't have any digital certificate for this signed document" window will pop up. I have also encountered this problem, and the maintenance and installation are invalid. The reason is that a higher version of Adobe Acrobat 9 Pro was used before, and a lower version of Adobe Acrobat 7 Pro was installed when reinstalling the system, which caused this problem. Solution: uninstall Adobe Acrobat 7 Pro；; Reinstall Adobe Acrobat 9 Pro, and the problem will be solved.
