Feedback? Comments? Questions?

Please give feedback and feel free to join the discussion at the current official thread: Wrye Bash (Oblivion, Skyrim, Skyrim SE, Fallout 4). Be sure to read the first post for information on installation, troubleshooting, reporting bugs etc. If you are having trouble, you'll find many friendly people there who can help.  Check out the 2nd post to see the list of known bugs, and, more importantly, whether the bug has already been fixed.


Basic information is in the OP of the Wrye Bash topic at the BethSoft 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 Skyrim 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, however, allows you to follow the rapidly developed code and is therefore preferred.

Dependency installation for the Python version will be handled automatically by the installer. However, if you want or need to do things manually, see the installation sections on the General Readme for information, and the Advanced Readme for detailed instructions.

Note that the 32-bit versions are required even if you are on a 64-bit operating system

  • For manual installations of either the Standalone or Python versions, extract the archive in your Skyrim game folder so that the Mopy directory appears in the Skyrim 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! In Windows Vista and up, don't install Skyrim Special Edition in the Program Files folder due to User Account Control!
