Since I installed Classic Client, my cards from other vendors do not work, their certificates are no longer accessible.

Applies to

All Classic Client versions on Microsoft Operating Systems

Classic Client uses a proprietary tool, the Registration Tool (regtool.exe) to register the card certificates in the Microsoft Certificate Store. During the Classic Client installation, the Microsoft certificate propagation is therefore disabled.

However, the Registration Tool will only register certificates for known cards. If you use another unknown card you may no longer be able to access its certificates.

Re-enabling the Microsoft certificate propagation would solve your issue.

On Windows XP, Windows Server 2003

Set the following registry key to 00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\ScCertProp]
"Enabled"=dword:00000001

On Windows Vista, Windows 7, Windows Server 2008 R2

Set the following key to 00000001 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CertProp]

"CertPropEnabled"=dword:00000001

And start the service: Certificate Propagation.

More information

If you have got two cards and have installed two middleware on your computer to use these cards there might be an incompatibility. This is very likely if one of the middleware support both cards.

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.
