Download

The easiest way to install GNS3 on Windows is to use the "all-in-one" installer that can be downloaded from our download section.

Installation

Find the file you downloaded and double-click on it to begin the installation. Everything else is a matter of clicking on next button if you don't want to customize your installation.

GNS3 depends on several other programs to operate. Those software dependencies include WinPcap, Dynamips and Qemu to name a few.

These main components along with GNS3 are all chosen by default for installation. The default location to install GNS3 is also chosen for you.

Moreover note that if needed, WinPcap Setup Wizard will be launched for you to install it, this dependency is required for GNS3 to communicate with real networks through a physical network internal controller. Make sure that the "Automatically start the WinPcap driver at boot time" check box is ticked.

Once the installation completed, click the Start button, All Programs, GNS3, and then choose GNS3 out of the list of applications installed. The GNS3 graphical interface will start.
