4.15. Windows: NSIS (optional)

The NSIS (Nullsoft Scriptable Install System) is used to generate Wireshark-win32-2.5.0.exe from all the files needed to be installed, including all required DLLs, plugins, and supporting files.

To install it, download the latest released version from http://nsis.sourceforge.net. NSIS v3 is recommended and may be required in the future. You can also install it using Chocolatey:

PS$> choco install nsis

You can find more instructions on using NSIS in Section 3.11.4, “Win32: NSIS .exe installer”.
