Wrye Flash is a powerful mod management utility adapted to Fallout New Vegas by Valda from the TES IV: Oblivion and TES V: Skyrim versions.

Its features include:

  • A mod installation and conflict manager
  • A plugin load order manager
  • Increased mod compatibility
  • Lifting of the 255 plugin limit through automatic merging of compatible mods
  • .ini and settings files tweak management
  • Screenshot management
  • Many, many more features

Wrye Bash can appear daunting at first. To help make it more manageable, the documentation has been split into a few readmes that are targeted towards different usage requirements.

The General Readme covers only the most commonly used features, so that the average user can start using Wrye Bash without being overwhelmed. Information on the less commonly used features and more technical details of the features covered in this readme may be found in the Advanced Readme. Information on some of the syntaxes and file formats that Wrye Bash uses are found in the Technical Readme.

Note that this version is not being updated at this time. Compatability for Fallout New Vegas will be added to the Oblivion and Skyrim version in the future


This documentation is for the Oblivion version but some still applies since this version of Wrye Flash is based off of Wrye Bash for Oblivion. Some of this will not apply until this version is integrated into the Oblivion and Skyrim version. So please do not post asking why the documentation mentions a feature that is not available in Wrye Flash.

Old Wrye Bash Documentation: This only covers Wyre Bash up until version 271.

Installation from GitHub

You can get Wrye Flash from this mirror link on GitHub.

1. Click the download Zip file. It will give you a file named garybash-sharlikran-falloutnv-support.zip
2. Unzip that and go into the folder named garybash-sharlikran-falloutnv-support
3. Then you will see 3 folders, Data, Mopy, scripts
4. Copy only Data and Mopy to your FalloutNV folder where the FalloutNV.exe is located.  Overwrite the files if needed.

3. You will see 2 folders, Data and Mopy
4. Copy Data and Mopy to your FalloutNV folder where the FalloutNV.exe is located.  Overwrite the files if needed.

Additional Installation Notes
First, if you're using Windows XP, Wrye Flash needs the MSVC++ 2005 SP1 Redistributable with ATL Security Update installed, the x86 version. This is required for the custom 7z executable that Wrye Bash uses to run. Later versions of Windows already have this installed.
This is a Python version, so install the dependencies manually until there is in automatic installer.

Note that the 32-bit versions are required even if you are on a 64-bit operating system
Python 2.7.3
wxPython unicode for Python 2.7
comtypes 0.6.2
PyWin32 for Python 2.7

Other setups may work, but this is the only officially supported setup.
Python 3.x: NOT supported
5. Go to the Fallout New Vegas folder, then the Mopy folder and, run Wrye Bash Launcher.pyw (this is the exe file for Python)
