How to Install

A Comprehensive Guide to Installing Skyrim Script Extender (SKSE)

Skyrim Script Extender, commonly known as SKSE, is an essential tool for enhancing Skyrim with complex mods. Its installation may seem daunting for first-timers, but fear not, as this guide will walk you through the process in a clear and concise manner.

Step 1: Identifying Your Skyrim Edition

With multiple versions of Skyrim available, identifying your specific edition is crucial. For those with the Skyrim Special Edition or Skyrim Anniversary Edition, and keeping your game updated through Steam, opt for the current Anniversary Edition build of SKSE.

If you prevent Skyrim from updating on Steam, determining your exact version is necessary. Accomplish this by:

Opening Steam, navigating to your library, locating Skyrim, right-clicking to select ‘Properties’, then ‘Manage’, and finally ‘Browse local files’.
In the game install directory, find and select the file named ‘SkyrimSE’.
Right-click, select ‘Properties’, then navigate to the ‘Details’ tab.
Note the version number listed here.

With your Skyrim version identified, return to the SKSE website to download the corresponding SKSE version. Access to older versions of SKSE is also available through the website’s archive link.

Step 2: Preparing for Installation

Once the SKSE file is downloaded, save it to a convenient location, such as your Downloads folder. The next step involves extracting the files, requiring a tool like 7-Zip or WinRAR. While WinRAR has been known for its persistent purchase reminders, 7-Zip (available at 7-zip.org) is a reliable and less intrusive alternative. Install 7-Zip by downloading the 64-bit version and running the executable, following the default installation process.

Step 3: Extracting and Installing SKSE

Navigate to your downloaded SKSE .7z file, right-click, and select ‘Show more options’ if you’re on Windows 11, then choose the 7-Zip menu item. From there, select ‘Extract files’. Once extracted, you’ll see a new folder containing SKSE.

Copy all files from this uncompressed folder and paste them into your Skyrim game directory. This directory is accessible through Steam, as previously described.

Step 4: Launching Skyrim with SKSE

To ensure mods requiring SKSE work correctly, launch Skyrim using the SKSE executable. For convenience, create a shortcut to the SKSE executable on your desktop or add it to Steam.

Once installed, no additional steps are needed to launch Skyrim with SKSE’s added functionality. The Steam in-game overlay must be enabled for this integration to work. If you prefer running without the overlay, start Skyrim by launching skse_loader.

If you use multiple Steam libraries, please make sure to install SKSE to the same library that you have chosen for Skyrim.

By default, this installation will automatically update to the latest version of SKSE when released. If you prefer to stay on an older version, they will be available via the “betas” tab, allowing you to pick an older build.

FAQs

Are there any compatibility issues with SKSE and Skyrim updates?

Yes, compatibility issues can arise when Bethesda releases updates for Skyrim. These updates can change the game’s code structure, which may cause SKSE and mods relying on it to work improperly or not at all until an updated version of SKSE is released. To mitigate these issues, modders often recommend disabling automatic updates for Skyrim in your Steam settings and only updating manually after confirming that SKSE and your essential mods have been updated to be compatible with the new game version.

How do I get Skyrim Together to work with script extender?

Skyrim Together only works with skse 2.00.19 and also only game version 1.5.97 (pre AE).

Can SKSE affect game performance or stability?

SKSE itself has minimal impact on game performance and stability since it primarily extends the scripting capabilities available to mods. However, the mods that require SKSE can vary greatly in their effect on performance and stability depending on their complexity and how well they are coded. It is always a good idea to monitor your game’s performance and stability as you install new mods and to read mod descriptions and user feedback to be aware of any potential issues.

How do I troubleshoot issues with SKSE or SKSE-based mods?

Troubleshooting SKSE or mods that depend on it typically involves a few steps:
Ensure you have the latest version of SKSE installed and that it matches your version of Skyrim.
Verify that the mod installations are correct and that they are compatible with your game version and other installed mods.
Use mod management tools to check for mod conflicts and resolve them.
Consult the mod’s documentation and community forums for specific troubleshooting advice related to the mod.
As a last resort, you can try reinstalling SKSE and your mods, ensuring to follow installation guides closely.

Is SKSE available for all versions of Skyrim?

SKSE is available for both the original Skyrim (often referred to as “Skyrim Classic”) and Skyrim Special Edition. Each version of the game requires a specific version of SKSE, so it’s important to download the correct one from the SKSE website. There is also a version for the Skyrim VR, addressing the unique needs of virtual reality gameplay.

Can I use SKSE with mods downloaded from Bethesda’s in-game mod system?

Yes, SKSE can be used with mods downloaded from Bethesda’s in-game mod system, as long as those mods are designed to work with SKSE.

It’s important to carefully read mod descriptions to understand their requirements and installation instructions.

What are some popular mods that require SKSE?

Some popular mods that require SKSE include SkyUI, which overhauls the game’s user interface to be more PC-friendly; Frostfall, a survival mod that adds temperature and weather survival elements to the game; and Convenient Horses, which vastly improves horse mechanics and interactions. These mods showcase the range of enhancements SKSE enables, from interface improvements to gameplay overhauls.
