PRTG Manual: Activate the Product

PRTG Network Monitor automatically activates your license via the internet during the installation process. If PRTG cannot access the activation server, you must manually activate your license.

i_round_redYou must complete the product activation process once to use PRTG, otherwise it does not run. Do not forget to activate your commercial license when you want to upgrade your Trial Edition or Freeware Edition installation.

Online Activation

Because PRTG already asks for a key during installation, you usually do not need to manually enter one afterward. However, there are still scenarios where you need to change your key and activate the respective license. For example, you must provide your Commercial Edition license key if you have purchased the Commercial Edition and want to upgrade your Freeware Edition or Trial Edition, or if you upgrade a Commercial Edition license to a higher edition.

  1. To enter a new license key, log in to the PRTG web interface.
  2. Select Setup | License Information from the main menu bar.
  3. Click Change License Key. The Update Your License page appears where you can activate your new license.
  4. Select the activation type Automatic (online activation with optional HTTP proxy) if your PRTG core server can connect to the internet.

  5. Enter your license information and click Update License.
  6. PRTG connects to the Paessler activation server on port 443 and validates your license.

If everything works fine, you see the message Activation was successful as License Status at the top of the page.

i_round_blueThe PRTG core server needs an internet connection on port 443 to activate. If a proxy connection is needed, see step 3 on the Update Your License page. If the activation fails, you can also try an offline activation.

Offline Activation

If no internet connection is available, you must activate PRTG manually:

  1. In the PRTG web interface, select Setup | License Information from the main menu bar.
  2. Click Change License Key. The Update Your License page appears where you can activate your license.
  3. Select the activation type Manual (offline activation).
  4. Enter your license information and follow the instructions of step 3b and step 4 on the Update Your License page.
  5. Click Update License.

If the activation was successful, you see the message Activation was successful as License Status at the top of the page.

i_round_redIf your PRTG core server is offline, you need to manually activate your license after you renew your maintenance. This ensures that you can install updates, for example. Your maintenance information has to be the same as in the PRTG installer, so you need to activate your license offline before you install an update.
