To install Skyrim Script Extender (SKSE) for version 1.5.97 (often called the "Pre-Anniversary Edition" or "Rollback" version), you must download a specific legacy build rather than the latest version on Steam or the SKSE website. 1. Download the Correct Version

Because Skyrim version 1.5.97 is older than the current "Anniversary Edition" (v1.6+), you cannot use the standard "Current Special Edition build." Go to the official SKSE website.

Look for the Archived Builds section or the link for "Current SE build 2.0.20 (runtime 1.5.97)".

Warning: Do not download the build labeled for 1.6.x (Anniversary Edition), as it will not be compatible with your game version. 2. Manual Installation Steps

Extract the Files: Open the downloaded .7z file using a tool like 7-Zip.

Locate Game Folder: Find your Skyrim directory (usually SteamApps\common\Skyrim Special Edition). It should contain the SkyrimSE.exe file.

Copy Files: Drag and drop the following files into that game folder: skse64_loader.exe skse64_1_5_97.dll skse64_steam_loader.dll

Install Scripts: Open the Data folder inside the SKSE archive. Copy the Scripts folder and paste it into the Data folder inside your Skyrim directory. 3. Launching and Verifying

To use SKSE, you must not launch the game through Steam or the standard launcher.

Launch: Run the game using skse64_loader.exe. You can right-click this file and select "Run as administrator" for better stability.

Verify: Once in the game's main menu, open the console (tilde key ~) and type getskseversion. If it returns 2.0.20, the installation was successful.

Because 1.5.97 was a messy update for Bethesda (they accidentally left "Creation Club" data inside the main game files), you must clean the master files, or many mods will crash your game.

Prerequisite: Download SSEEdit from Nexus Mods.

Most Wabbajack modlists (like Living Skyrim 4 or Wildlander) require 1.5.97 automatically. The installer handles the downgrade for you.
