The ActivIdentity ActivClient (Athena IDProtect Duo PIV) driver helps Windows communicate with the associated smart card or security token for identity-based authentication. Used with compatible middleware and applications, it supports access to credentials stored on the device for tasks such as secure sign-in and certificate-based authentication.

Key Features

• Smart card communication: Provides the device support needed for Windows and compatible security software to interact with the Athena IDProtect Duo PIV.
• PIV credential access: Helps supported applications use Personal Identity Verification credentials for authentication and other certificate-based operations.
• Middleware integration: Works alongside compatible ActivClient components to connect the device with applications that require smart card credentials.
• Windows compatibility: Driver packages are available for supported configurations of Windows 11, 10, 8, and 7. Check the individual package requirements, as compatibility can vary by release and system architecture.

How to Install

1. Check your Windows configuration. Confirm your Windows version and whether your installation is 32-bit or 64-bit. Select a package that explicitly supports both your operating system and the ActivIdentity ActivClient (Athena IDProtect Duo PIV).
2. Download and review the package. Use a driver supplied by the manufacturer, and read any included installation notes. On an organization-managed computer, check with your IT administrator before changing smart card drivers or ActivClient software.
3. Run the installer. Close applications that use smart cards, then launch the setup program with administrator permissions. Follow its instructions about when to connect the token or insert the card into a compatible reader.
4. Complete any required setup. Restart Windows if prompted. Install compatible ActivClient middleware or reader drivers if the package instructions require them; the device driver alone may not provide every authentication function.
5. Verify recognition and access. Check Device Manager for device errors, then use your smart card management utility or approved application to confirm that the card and certificates are detected. Enter your PIN only when requested by trusted software.

If the device is not recognized, try reconnecting it, checking the reader connection, and confirming that the installed package matches your Windows version. Avoid repeated PIN guesses, which can lock the card; contact your administrator if credentials are unavailable or authentication still fails.

Common Issues and Fixes

• Install fails or rolls back: Close ActivClient/PIV software, uninstall older ActivClient and smart-card middleware versions, then run the installer as administrator. Reboot when prompted. If the MSI still fails, clear `%temp%` and confirm the Windows Installer service is enabled.
• Token not detected: Check that the Athena IDProtect Duo PIV is firmly connected and the Windows Smart Card service (`SCardSvr`) is running. Look for reader errors in Device Manager, reinstall the reader driver, and try another USB port without a hub. Confirm ActivClient middleware is running.
• Version conflicts: Remove duplicate PIV/CAC middleware and old ActivClient builds before installing the version matching your Windows architecture. After upgrading, reboot and reinsert the token. If certificates are missing, repair ActivClient and avoid mixing 32-bit and 64-bit components.
