Unregistered Card

This error indicates that your card is not recognized by the computer.

First check that the correct version of Classic Client is installed on your computer. If you have correctly installed the middleware then there may be a problem to access some registry keys.

The registry keys used to recognize smart cards are located in:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Calais\SmartCards

Right-click on the folder and select Permissions. Grant the Group SYSTEM Full Control and Users the Read permission.

If this does not solve your issue, you need to know your card Name to check its specific permissions. You can get the card name by running the SmartDiag tool on a working computer.

Example: Card = Classic TPC

Perform the same permission configuration in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Calais\SmartCards\Classic TPC

Mute Card

If the smart card name is [Mute Card] it means that your card cannot be read. Make sure it is correctly inserted in the smart card reader.

If it is correctly inserted, your card may be physically damaged, ask your administrator for a new one.

More information

On 64 bits Operating Systems you need to make modifications in the 32 bits part of the registry as well (Wow6432Node)

Some cards can have two names (Example: Classic TPC and Classic TPC WR). Launch the SmartDiag tool and in the Advanced View press twice the F5 key on the keyboard to refresh. It will show the second name. If your card has two names you should follow the procedure for both.

Note

Modifications to the operating system can lead to unrecoverable errors. Modifications are reserved to advanced users. If you do not feel confident we recommend creating a System Restore Point before performing changes.
