I have a problem with digital signature. I use Windows 10 (64 bit) and Adobe Acrobat DC. I have an intelligent card that contains my digital certificate. (Other softwares work fine.) When I use the certificate menu in DC I can choose my certificate. The program fills the visible box with my name etc. When I click the signature button DC says 'windows cryptographic service error: access denied. Code: 2147942405'.
DC does not ask for my PIN code for the intelligent card.
My certificate was imported into windows certificate store. All the necessary programs run and all devices work fine.
The Microsoft Community says it is not MS's responsibility try to ask Adobe.
Please help me.
