Messages regarding Registry changes required for data safety may appear when you login to a Company. Registry changes are typically made during installation.
If changes have been made you will be prompted to restart Windows so the changes take effect. Alternatively, if changes could not be applied, either run Accredo as Administrator and allow it to make registry changes, or have the network administrator apply the registry changes documented below. Restart Windows after the changes are made.
