<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> 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.

You 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 license key during installation, you usually do not need to manually enter one afterward. However, there are still scenarios where you need to change your license key and activate the respective license. For example, you must provide your commercial edition license key if you want to upgrade from a freeware edition or trial edition, or if you want to upgrade your commercial edition license to one with a higher sensor count.

To enter a new license key, follow these steps:

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

Without internet access, you must select Manual (offline activation). The activation process works a bit differently in this case and requires manual interaction. See section License Information for more information.

Enter your license information and click Update License.
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.

The 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.

For more information, see section License Information.

Offline Activation

The following process only applies to PRTG Network Monitor. If you use PRTG Enterprise Monitor, see the Paessler website: How to use PRTG Enterprise Monitor in an offline environment in 5 steps.

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

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

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

For more information, see section License Information.

If your PRTG core server is offline, you need to manually activate your license each time. This makes sure 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.
