eSigner 3.X versions
The fact that a logon button is displayed indicates that eSigner can start. However eSigner is not able to communicate with the card.
If Classic Client works fine then eSigner may not be able to find Classic Client with the PKCS11LibraryName registry key.
Find the Classic Client gclib.dll file and copy the path in the registry.
Example with default path:
"PKCS11LibraryName"="C:\Program Files\Gemplus\\GemSafe Libraries\\BIN\GCLIB.dll"
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.
