## 2.6 Upgrade and Uninstallation - Windows

### Upgrade

Simply run the installation of a new version to upgrade WinRoute (i.e. to get a new release from the Kerio Web pages — http://www.kerio.com/).

All windows of the Kerio Administration Console must be closed before the (un)installation is started. All of the three WinRoute components will be stopped and closed automatically.

The installation program detects the directory with the former version and updates it by replacing appropriate files with the new ones automatically. License, all logs and user defined settings are kept safely.

Note: This procedure applies to upgrades between versions of the same series (e.g. from 6.6.0 to 6.6.1) or from a version of the previous series to a version of the subsequent series (e.g. from 6.5.2 to 6.6.0). For case of upgrades from an older series version (e.g. 6.3.1), full compatibility of the configuration cannot be guaranteed and it is recommended to upgrade “step by step” (e.g. 6.3.1 → 6.4.0 → 6.5.0 → 6.6.0) or to uninstall the old version along with all files and then install the new version “from scratch”.

### Update Checker

WinRoute enables automatic checks for new versions of the product at the Kerio Technologies website. Whenever a new version is detected, its download and installation will be offered automatically.

For details, refer to chapter 16.3 Update Checking.

### Uninstallation

To uninstall WinRoute, stop all three WinRoute components. The Add/Remove Programs option in the Control Panel launches the uninstallation process. All files under the WinRoute directory can be optionally deleted.

(the typical path is `C:\Program Files\Kerio\WinRoute Firewall`)

— configuration files, SSL certificates, license key, logs, etc.

Keeping these files may be helpful for copying of the configuration to another host or if it is not sure whether the SSL certificates were issued by a trustworthy certification authority.

During uninstallation, the WinRoute installation program automatically refreshes the original status of the Windows Firewall / Internet Connection Sharing, Universal Plug and Play Device Host) and SSDP Discovery Service system services.
