Acrobat Professional 2020 encryption error
I have recently bought and install Adobe Acrobat Pro 2020. Whenever I try to encrypt a PDF file, the "Apply" button does not react to clicking. When I then choose "encrypt with password" from the dropdown menue and go through the menu, I get the following error at the end of the procedure:
"Allgemeiner Fehler des Kryptografiesystems". The PDF file is not encrypted and nothing else happens. I already tried the following:
1) repair of installation
2) full wipe of the installation and clean re-install
3) resetting all settings in the app
It is the extact copy of a similar error by another user (WernerGg). You can find the thread when you search for the following keywords: "Allgemeiner Fehler des Kryptografiesystems". Unfortunately this thread ends without a solution.
Could you please hlep me in fixing the error? Thank you very much.
