Prerequisites:

  • Remove all smart cards from smart card readers.

  • Manually unregister ActivClient PKCS#11 extension from these applications. See Firefox and Thunderbird Support.

  • Restart Firefox and/or Thunderbird.

  1. Go to the program or app management feature on your system.

  2. Select ActivClient from the list and click Uninstall.

    A confirmation message is displayed.

  3. Confirm your choice and click Yes.

When ActivClient is uninstalled, the ActivClient policy settings remain on the workstation. For instructions on how to uninstall them, refer to the Uninstalling the ActivID ActivClient Administrative Templates.

Note: Starting from ActivClient 7.4, uninstalling ActivClient will require a manual reboot. No reboot prompt is displayed to the user.
Important:

Due to the deprecation of Visual Basic Script (VBScript) starting with Windows 11, version 24H2, uninstalling ActivID ActivClient on this and later Windows versions may encounter issues. To troubleshoot problems with uninstalling ActivClient caused by the VBScript deprecation, see Troubleshooting Uninstallation of ActivClient After Deprecation of Visual Basic Script.

This same issue may occur when upgrading ActivID ActivClient 7.4.3 to a higher version. To avoid problems with upgrading ActivClient caused by the VBScript deprecation, we recommend to uninstall your current version before upgrading to a higher one. For more details, refer to Troubleshooting Uninstallation of ActivClient After Deprecation of Visual Basic Script.
