PRTG Manual: Install a PRTG Core Server
Installing PRTG works like other Windows-based applications. To install PRTG, run the installation setup program from the .zip file that you have downloaded.
This only applies to PRTG on premises installations, not to PRTG hosted by Paessler instances.
Confirm the question of the Windows User Account Control with Yes to allow the program to install. The installation dialog guides you through the installation process.
Select a language for the program and click OK. The available language options depend on both your Windows version and the setup file.
Accept the license agreement and click Next.
Enter your email address to make sure you receive important system alerts and click Next.
PRTG is now being installed on your computer.
Select Yes, restart now (STRONGLY recommended!) to complete the installation of PRTG and use all its functionalities after the restart. Click Finish to complete the PRTG Network Monitor Setup Wizard.
After installation, you can open the PRTG web interface in your system's default browser. Make sure Google Chrome 72, Mozilla Firefox 65, or Microsoft Internet Explorer 11 is available on the system, and set as default browser (see section System Requirements).
In certain cases, antivirus software like Windows Defender interferes with the PRTG installer. This might cause high CPU load on the PRTG core server, which might prevent a successful installation. Temporarily disable Windows Defender and other antivirus software in these cases.
PRTG validates your license information during the installation process by connecting to the activation server. If there are issues with the trial installation, PRTG asks you for your License Name and Key. In this case, you are directed to our website.
Enter both License Name and License Key exactly as received from Paessler. We recommend that you use copy and paste to avoid mistakes.
For more information, see section Enter a License Key.
If you think that you have correctly entered your license information but get a License Invalid message, contact [email protected].
You can find the label License Owner in some documents from the Paessler shop. License Owner is the same as License Name, for which you might be asked while installing PRTG or when you change your license key.
When you update a commercial version with a new trial installer, the new trial license key is ignored.
