compila e firma - errore sconosciuto

[Zorzi Impianti]

Buongiorno, 

purtroppo non riesco più a porre una firma a nessun file in quanto, qualsiasi firma decido di utilizzare, me la fa selezionare dall'elenco e poi mi appare la scritta "errore sconosciuto". 

Come risolvo il probelma?

Hi Zorzi

Hope you are doing well and sorry for the trouble. As described you are unable to sign the document and get the unknown error

Is this a behavior with a particular PDF file or with all the PDFs? Please try with a different PDF file and check.

What is the version of the Adobe Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the latest version 21.01.20149 installed. Go to Help > Check for Updates and reboot the computer once.

If it still doesn't work, please try to turn off the protected mode for testing (Win Only) Go to Edit > Preferences > Enhanced Security > Uncheck 'Enable protected mode at startup' turn off the protected mode and Uncheck 'Enhanced Security' > Click OK and reboot the computer.
Note: Please turn on the security after testing to avoid any security risk.

You may also try to sign the PDF online at https://documentcloud.adobe.com/link/home/ and see if that works for you.

Regards

Amal
