Description

This plugin is designed to remove the current 2GB limit in NSIS by creating and extracting images contained in .wim files that are separate to the installer. Thanks to the Wim API being unicode only, this plugin is unicode only. This plugin requires Admin privileges to run correctly (blame the API for that one too). Also requires Windows 7 or later. 32 bit and 64 bit plugins are included.

Just extract the contents to your nsis directory (usually 'C:\Program Files\NSIS').
