What does Wrye Bash do?

Wrye Bash is a powerful mod management utility for games based on Bethesda's Creation Engine. A few of its countless features are:

  • Mod installation and file conflict management
  • Plugin load order management
  • Screenshot management
  • .ini tweak management
  • Clean uninstallation of mods, even conflicting ones
  • The "Bashed Patch", which allows you to increase the compatibility of mods, configure the game to your liking via tweaks and to surpass the 255 plugins limit by merging patches into it

Basic information is in the OP of the Wrye Bash topic at the AFKMods forums linked to above. For more information visit:

The General Readme can be launched from inside Bash by clicking the question mark icon on Bash's toolbar.

Requirements and Installation:

Short version:

Just use the installer and install to the Oblivion folder! When you install dependencies, just install them to their default locations.

Long version:

There are two versions available: the Python version and the Standalone version. They are functionally equivalent. Most people should run the Standalone version since it is slightly simpler (no external Python components to install). The Python version allows you to follow the rapidly developed code.

Dependency installation for the Python version can be automated with pip. See the installation sections on the Advanced Readme for detailed instructions.

Note that the 64-bit versions are required, we no longer support 32-bit operating systems.

  • For manual installations of either the Standalone or Python versions, extract the archive in your Oblivion game folder so that the Mopy directory appears in the Oblivion directory
  • For Python versions, run by double-clicking on Wrye Bash Launcher.pyw
  • For WBSA (Wrye Bash StandAlone), run by double-clicking on Wrye Bash.exe

Remember, don't install Oblivion in the Program Files folder due to User Account Control!
