Downloading PRTG Network Monitor

Please download the latest publicly available program version from the Paessler website. Simultaneously, you will receive a trial key. Enter this license key during the installation of PRTG. If you have already purchased a commercial license, use your commercial key. Please log in to the Paessler website to find your license key,

Every freeware installation starts as a trial version that allows you to use an unlimited number of sensors for 30 days. After the trial period has expired, your installation automatically reverts to the freeware edition with 100 sensors. Please understand that customers with a commercial license get prioritized support.

To upgrade your running trial or freeware version to a commercial edition, please purchase a commercial license key on https://shop.paessler.com and enter this key on the license page in the PRTG web interface.

Updates are free to customers with an active maintenance contract. If you do not have an active maintenance contract, please log in to the Paessler shop to renew it or contact sales@paessler.com.

icon-i-round Once installed, the PRTG Software Auto-Update will automatically download and install new software versions. This helps you keep PRTG up to date without manually installing new PRTG versions.


Double-click the setup file on the computer you want to use as PRTG server. Follow the installation wizard and install the software.

At the end of the installation, PRTG opens a new browser window automatically. It connects to the PRTG web interface, shows the device tree, and starts the setup assistant. Please make sure you load the web interface with one of the supported browsers:

  • Google Chrome 49 or later (recommended),
  • Mozilla Firefox 45 or later, or
  • Microsoft Internet Explorer 11.

We recommend that you use Google Chrome to access the PRTG web interface. Firefox has security issues and Internet Explorer as well as Microsoft Edge might have issues with some functionalities. See Detailed System Requirements for more details.

icon-i-round Due to scripting incompatibilities, you might not be able to use all functionalities of the PRTG Ajax web interface with Internet Explorer 10 or earlier and other older browsers. If you cannot access the PRTG web interface, please open the URL of PRTG in another browser.


If everything works fine, the first thing you will see will not be the login screen, but the device tree. You only have to log in manually if you use a different browser.
