Installing Netgen using the NSIS Installer

Most important in short

  • if you don't have Microsoft Visual C++ 2008 installed, you have to install the Redistributable Library Package from

(win32 download) or (x64 download)

  • you can install Netgen as normal user in your local user folder, or you can run the installer in administrator mode to install Netgen to the program folder

The Basics

On the Windows platform, Netgen is available as a packaged installer created using the open source Nullsoft Scriptable Install System (NSIS). This simplifies the process of installing Netgen on Windows to just a couple of mouse clicks.

Two versions of the installer are available for different platforms and can be downloaded from the Netgen Mesher Download page:

  • 32-bit Version: Netgen-4.9.11_Win32.exe
  • 64-bit Version: Netgen-4.9.11_Win64.exe

Note: The Netgen Mesher Installer is designed to allow installation of the utility without the need for Administrative rights on the Windows system. In other words, the Netgen Mesher can be installed by normal users of the system.


The installer contains all the dependencies required by the Netgen Mesher. However, to prevent conflicting or repetitive versions of the auxiliary programs from being installed unnecessarily, the installer first checks whether the following libraries are available in the system path before installing local copies of them in the Netgen install folders:

  • Tcl 8.5
  • Tk 8.5
  • Tix 8.4
  • Togl 1.7
  • pthreads
  • OpenCascade run-time (only if installing Netgen with OCC support)
  • Lapack/BLAS run-time (only if installing the NGSolve add-on package)

(Note: This check performed is very rudimentary, and non-standard configurations or installations of the various packages may prevent them from being found by the Installer...)
