The validity of the PDF document signature cannot be verified
If you have Adobe Acrobat or Adobe Reader installed by default, when you open a document that contains an electronic signature, the list of trusted service providers is automatically updated. This list already includes the I.CA root certificate which is needed for validating the electronic signature of PDF documents.
If you have automatic updates disabled, you can use manual updates via the menu "Edit", "Preferences", "Rights Manager", menu automatic update "Update". (valid for version 11).
