Skyrim Script Extender (SKSE)
by Ian Patterson, Stephen Abel, Paul Connelly, and Brendan Borthwick (ianpatt, behippo, scruggsywuggsy the ferret, and purple lunchbox)

Current classic build 1.7.3: install via steam - installer - 7z archive (readme, whatsnew)

The link below is a preliminary build of SKSE64 with support for Skyrim SE 1.6.318, aka the Anniversary Edition. The plugin manager has been updated with a new versioning system to handle post-AE plugins. If you are a plugin developer, please read PluginAPI.h for the breaking change regarding how plugins report their versions and compatibility with different runtimes.
If you have an existing mod setup on pre-AE that you would like to keep working, this is not a sign that you should upgrade and start using this version of SKSE. However, if you have already upgraded to AE and are feeling adventurous, then try this out.

Preliminary AE build 2.1.3 (runtime 1.6.323): 7z archive

Current SE build 2.0.20 (runtime 1.5.97): 7z archive

Current VR build 2.0.12 (runtime 1.4.15): 7z archive

Having trouble extracting the archive? Install via Steam, use the installer, or download 7-zip. DO NOT USE ANYTHING FROM THE WINDOWS APP STORE.

If you are having trouble with the installation instructions, please watch this video.

Compatibility:
SKSE will support the latest version of Skyrim available on Steam, and only this version (currently 1.9.32 with any other numbers following). It is extremely unlikely that any future non-SE Skyrim updates will be released.

SKSE cannot support any potential Windows Store release of Skyrim. Windows Store applications are locked down similarly to consoles and do not allow the APIs necessary for script extenders to work.

Contact the SKSE Team
Having crashes on startup after a game patch? Remove the files from Data/SKSE/Plugins and try again. Mods using plugins probably need to be updated.
Before contacting us, make sure that your game launches properly without SKSE first. Also, attach skse.log, skse_loader.log, and skse_steam_loader.log (found in My Documents/My Games/Skyrim/SKSE/) to any support requests.
