I have cryptovision installed and have started the cryptovision Utility module. I see the messages "No valid smart cards found, exiting" or "Windows cannot load the necessary driver software. Code 31" displayed. What should I do?

Update the smart card reader driver to the Microsoft Usbccid Smartcard reader driver (WUDF) in the Windows Device Manager.
