PRTG Manual: Activate the Product
PRTG automatically activates your license via the internet during the install process. If PRTG cannot directly connect to the internet and therefore cannot access the activation server, you have to manually activate your license.
You have to 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 or freeware installation!
This only applies to PRTG on premises instances, not to PRTG hosted by Paessler.
Usually, you do not need to manually enter a key after the installation to activate it because PRTG asks for it during the install process. However, there are still scenarios where you need to change your key and activate the respective license. You have to provide your commercial license key, for example, if you have purchased a Commercial Edition and want to upgrade your running Freeware or Trial Edition, or if you upgrade an existing commercial license to a higher edition.
- To enter a new license key, log in to the PRTG web interface.
- Select Setup | License 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 server can connect to the internet.
Without internet access, you have to select Manual (offline activation). The activation process works a bit differently in this case and requires manual interaction. - Provide your license information and click Update License.
- PRTG connects to the Paessler activation server via SSL 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.
For details, see section PRTG Status—Licensing Status and Settings: Update Your License.
The PRTG core server needs an internet connection on port 443 to activate. If a proxy connection is needed, configure it in step 3 on the Update Your License page. If the activation fails, you can also try an offline activation.
This option is not available in PRTG hosted by Paessler.
If no internet connection is available, you have to activate PRTG manually.
This option is not available in PRTG hosted by Paessler.
- In the PRTG web interface, select Setup | License 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) if your PRTG server cannot connect to the internet.
- Provide your license information and follow the instructions in step 3 and step 4.

If the activation was successful, you see the message Activation was successful as License Status at the top of the page.
For details, see section PRTG Status—Licensing Status and Settings: Update Your License.
If your PRTG server is offline, you need to manually activate your license after renewing your maintenance. This ensures that you can install updates, for example. Your maintenance information has to fit the PRTG installer, so you need to activate your license offline before you install an update.
