 Product change from Client Security to PSB Workstation Security results in a "trial period has ended" error



The customer has been using a trial version of F-Secure Client Security (CS). After having tried out CS, the customer decides to start using PSB Workstation Security instead. The customer uninstalls CS and installs PSB Workstation Security. The installation is completed without issues, but a notification that the trial period has ended or will expire in 30 days is shown to the user.


After the uninstallation of the CS trial version, there are still some remaining items left from the previous installation. When the customer installs PSB Workstation Security, the sidegrade does not detect anything as CS has been already removed by the customer.


To get rid of the trial period notification:

  1. Remove the Client Security registry key fromĀ HKEY_LOCAL_MACHINE\SOFTWARE\Data Fellows\F-Secure\TNB.
  2. Restart the F-Secure Management Agent (FSMA) service.
The notification about the trial period should now have disappeared. If you have not yet installed PSB Workstation Security on the client, you can proceed to install it now.
