About this mod

The Neverwinter Nights Installer Tool (NIT) is designed to make it easy to manage, install and uninstall your Neverwinter Nights and Enhanced Edition mods. The tool makes it safe to try out new mods because it restores everything to the way it was when you use NIT to uninstall mods.

  • Works with Neverwinter Nights and the Enhanced Edition.
  • Automated conversion of movie files for the Enhanced Edition (BIK to WBM formatted files using FFmpeg).
  • Maintain Steam Workshop Subscription content so you can play Neverwinter Nights without running Steam or starting the game via a Steam shortcut. This feature also allows you to specify an alternative location for the User Files folder (Documents\Neverwinter Nights).
  • Constructs a Mod Installer from a variety of source file formats including BioWare Premium Module Installers, Zip, 7-Zip, WinRar and Exe files containing compressed contents as well as Community Patch Project (CPP) files. A Mod Installer is a NIT created folder containing all the files that need to be installed to use a Mod.
  • Configure how files are associated with Neverwinter Nights folders using "maps" for file extension names, special folder and file names as well as an "exclude" list to ensure unwanted files are not included in your Mod Installers.
  • Detects and resolves conflicts between different mods.
  • Record information about each of your mods (Rating, Notes, link to download page, best weapon to use, etc).
  • Categorise your mods into Groups to make long Mod lists more readable by breaking them into smaller sections and help deal with file conflicts.
  • Create Restorer packages of the original Neverwinter Nights installation so you are always able to restore overwritten files. A Restorer is a special Mod Installer containing original or unowned files that can be used to reinstate contents when a Mod is uninstalled as well as create backups of character and other unowned files.
  • Automated Restorer creation and maintenance of key files such as Neverwinter Nights INI and Database files.
  • Automated record of how long it took to complete playing a Mod or campaign.
  • Supports HAK patch files, which includes the automated generation and maintenance of the required INI file.
  • Publish your own Mods using the Tool to create and maintain compressed files containing your Mod's assets.


  • The Game Saves Manager allows you to play a number of Mods concurrently by moving your current game saves to a backup folder and then restoring a previous backup of the mod you want to play.
  • The Mod Explorer provides a view of all your Mods and associated Mod Information in a tabular format that you can filter using a wide range of criteria.
  • The Documentation Organiser makes it easy to review and copy Mod documents in downloaded files as well view existing documentation in your Mod Folder.
  • Use the Installation Manager to restore your favourite Mods after a fresh install of Neverwinter Nights or help track down problems with Mods that interfere with each other.
  • Use the Installation Analyser to view the contents of each of the Neverwinter Nights installation sub-folders as well as where each file was copied from.
  • Use the Installer Wizard Builder to provide more control over which files are used when a Mod Installer is created.
  • Use the Dependency Manager to define other Mods (eg CEP) required to play a specific Mod.
