Run the installation program (i.e.
kerio-pf-4.2.0-en-win.exe).
First, the program asks for selection of a language which will be use for guidance during the installation (English and German versions are available so far). This selection is applied only to the installation, whereas the user interface of the Kerio Personal Firewall can be switched to various language versions (for details, refer to chapter 6.3. Preferences).
In the next step, a path where Kerio Personal Firewall will be installed can be chosen,
(the C:\Program Files\Kerio\Personal Firewall
4 path is used by default).
In this stage, default mode of the firewall is to be chosen. We recommend unexperienced users to use the default Simple mode. Experienced users can use the Advanced mode (behavior of the firewall in this mode is identical as in previous versions of the Kerio Personal Firewall). Anytime, these modes can be switched between. For detailed information on default modes of the firewall, see chapter 2.2. Initial Configuration.
Restart is necessary after a successful installation, so that the Kerio Personal Firewall low-level driver can be enabled. Personal Firewall Engine will be started automatically upon a restart of the operating system (see chapter 4.1. Kerio Personal Firewall Components)
Warning: If you intend to use Kerio Personal Firewall with the AVG antivirus, AVG must be installed before the Kerio Personal Firewall installation is initiated. If Kerio Personal Firewall detects the AVG antivirus when the firewall is started first time, corresponding rules will be set for the antivirus (refer to chapter 9.3. Rules for AVG components).
Notes:
Memory dump which can be used when the system crashes is created in Windows NT operating systems. User can send it to Kerio Technologies — analysis of the dump may help find and remove bugs and errors which caused the crash.
Check an option (see chapter 6.3. Preferences) to set memory dump generating in the operating system.
If you use the Windows XP Service Pack 2 operating system or later, the installation program registers Kerio Personal Firewall in the Windows Security Center. During the installation, the firewall is registered as inactive.
Upon its startup, Kerio Personal Firewall disables the integrated Windows Firewall if it is running.
Under Windows 98, Me, NT 4.0 and 2000, update of the Windows Installer may be required unless it has been already updated (for example during another installation). Size of this update is approximately 1.8 MB. The up-to-date version of the installator must be downloaded and installed, otherwise installation of the Kerio Personal Firewall cannot be completed!
Installation of a new version (upgrade) is performed in the same method as a new installation described above. It is not necessary to stop running components of the application since they will be automatically stopped and closed by the installation program.
Note: Kerio Personal Firewall includes a built-in system for automatic checks and downloads of updates (for details see chapter 2.3. Update Checks).
Kerio Personal Firewall can be uninstalled using the Add / Remove programs option in the Control Panel. Files which have been created after the installation (configuration files, logs, etc.) will not be removed. After the uninstallation, these files can be either removed manually or kept for possible reinstallation.
Note: Under Windows XP Service Pack 2 and later, registration of the Kerio Personal Firewall in the Windows Security Center is scratched and the integrated Windows Firewall is enabled automatically upon uninstallation of the Kerio Personal Firewall.
