HostName Commander prompts you to enter your license key when you run it: simply press the Enter License Key button on the welcome screen and enter your licensing information into the form.

Alternatively, when the main window of HostName Commander is displayed, click on the little arrow next to the Help button in the menu bar, and choose About from the pop-down menu. Then click on the Register button in the dialog box.

IMPORTANT: When entering your licensing information, make sure you enter your name and the license key exactly as they are shown on your Registration Acknowledgment, including all capitalization and punctuation. Otherwise, HostName Commander may not accept the license key or may not register your information properly. You may wish to copy and paste the name and key from our message into the dialog box areas, to avoid typos.
