## 3.3 License information and import of the license key

License information is provided at the main page of Kerio MailServer. The Kerio MailServer main page is opened upon each startup of the Kerio Administration Console. It can be also displayed by clicking on Kerio MailServer in the sections list provided in the tree (see chapter 5.3 Administration Window).

Figure 3.5. Viewing license information

To run a full version of Kerio MailServer, a license key is required. A license key is a special file that must be imported to the product. Three methods can be applied to obtain the key (depending on the type of the product's registration and on the fact whether the product was registered in time):

- The license key is imported automatically during the product's registration in the administration console (see chapter 3.2 Registration with the administration console).

- Import via the context menu — click the right mouse button at the main page (see figure 3.5 Viewing license information) to open the context menu and select the Install license option (see figure 3.6 The main page's context menu). A standard file-opening dialog is displayed where the license key can be browsed and imported. If the import is successful, information about the new license is provided at the main page.

  If the new license increases number of licensed users, the Kerio MailServer Engine must be restarted upon the successful installation.

- Adding the license key file in the license directory manually — it is possible to copy the `license.key` file manually to the `license` subdirectory under the directory where Kerio MailServer is installed.

  If the file must be imported manually, it is necessary to stop the Kerio MailServer Engine before the import process is started.
