Example of License Information
License Name: John Q. Public
During the setup process, PRTG will ask you to enter your license information. Please use copy and paste to fill out the form in the dialog shown by the installer.
- Trial/Freeware license key: When entering a Trial license key, you can experience unlimited functionality of PRTG during the trial period. Your installation automatically switches to a Freeware Edition afterwards. For details about how to get your free Trial installer, please see Download PRTG section.
- Commercial license key: This key can only be entered if you install the Commercial Edition of PRTG, available for download in the customer service center. See Download PRTG section for details. Your installation allows the number of sensors according to your license.
Usually you do not need to enter a key manually, as it is prompted during installation. However, there are still scenarios where you want to change your key, for example, when switching from a Trial Edition to a Special Edition.
If you need to enter new license information, please follow these steps.
Step 1: Make Sure You Have Installed the Correct Edition
Please check first if you have installed the proper edition and then enter the license key.
There are two different installers available for PRTG (see Download section):
- The publicly available installer only contains the Freeware, Special, and Trial Editions. It does not accept any commercial license keys.
- The Commercial installer is only available for download to paying customers.
The Commercial Installer must be installed to run the commercial editions of PRTG Network Monitor. If you have purchased a license key for PRTG, please download and install the latest Commercial Installer from the Paessler website in order to apply your license key. Note: You can install a commercial version "on top" of an existing Trial Edition in order to maintain your configuration and monitoring data.
Step 2: Enter the License Key
You have two options to enter a license key. If you can login to the PRTG web interface, choose Setup | Enter License Key from the main menu bar and provide your license information. Alternatively, start the PRTG Administration Tool from the Windows Start Menu. In this program, select the License tab.
To use a PRTG license with this installation of PRTG, please enter the license information you have received from Paessler via email. To avoid typing errors, please copy and paste both the License Name and the License Key from the email. Both must be transferred exactly as shown in the email.
