Written By Jason Andrews

The modding community of Elder Scrolls V: Skyrim has breathed new life into the game, offering gameplay enhancements and vast customization options. Among these, the SkyUI mod has revolutionized the game’s user interface for a smoother and more intuitive experience.

But instead, Error Code 1 in SkyUI completely stops this beloved interface

That’s why, in this article, I’ll provide the verified techniques to resolve the SkyUI Error Code 1 on PC and Steam Deck and explain the steps to avoid modding issues in the future.

Why Do You Get Error Code 1 for SKYUI in Skyrim through SKSE?

When launching Skyrim via SKSE, the SKYUI Error Code 1 can pop up due to a lack of administrative privileges. It stops the mod from running correctly. Additionally, misconfigurations in SKSE64 or improper installation of game files can trigger this error.

Here are the reasons why you get the SKYUI Error Code 1 for SKYUI in Skyrim through SKSE:

  • Incorrect Installation Setup: You may have executed the installation process for SKSE inaccurately. Installing using SKSE is a complex process that needs your utmost attention to prevent any mistakes that could lead to errors.
  • Lack of Administrative Permissions: SKSE modifies the pre-existing Skyrim game, which means certain actions need elevated permissions. So, SKSE needs to run with administrative privileges. Otherwise, it’ll cause a SKYUI error.
  • SKSE64 Configuration Error: The SKSE64 file might not be adequately set up or could be misconfigured.
  • Misplaced Game Files: Putting game files in the wrong directory obstructs the game’s access to the required files during gameplay.

Now that you know what causes the SKYUI Error Code 1, let’s fix those issues one by one.

How to Fix SKYUI Error Code 1 in Skyrim

To resolve SKYUI Error Code 1, run SKSE as an administrator to properly access system resources. Also, ensure you’ve installed SKSE correctly and verify the game files through Steam to detect and fix any file corruption. Then, check the placement of the game folder.

Here are the methods to fix SKYUI Error Code 1 in Skyrim:

1. Run SKSE64 with Administrator Privileges

The Skyrim Script Extender (SKSE) is an essential tool with an elevated level of access to ensure its proper functionality alongside Skyrim and Steam. SKSE requires this high-level access due to how it interacts with these applications.

Here are the steps to run SKSE64 as an admin:

  • Open the drive where you’ve installed Skyrim.
  • Go to the following directory:
    STEAM > steamapps > common > Skyrim.
  • Right-click on the skse64_loader.exe file and choose Properties. skse-loader-properties
  • Go to the Compatibility tab and check the Run this program as an administrator option.
  • Click Apply and then OK. skse-run-as-admin

Now, relaunch the application and verify whether the SKYUI error code 1 error message appears.

2. Add Skyrim Script extender64 (SKSE) Correctly

If you encounter the SKYUI error 1 when launching Skyrim, the SKSE64 (Skyrim Script Extender 64) is likely not installed correctly. That’s why I’ve compiled two methods below that you can use to install SKSE64 effectively.

Here’s the process to add Skyrim Script extender64 (SKSE) correctly:

Install SKSE with Mod Manager 2

  • Open the Skyrim Script Extender web page and download the SKSE version according to your Skyrim version.

  • Create a desktop shortcut for the executable file in that folder and use it to launch Skyrim with SKSE.

3. Verify Game Files

Confirming the integrity of the Skyrim files verifies your game data to ensure all the files are available and there are no corrupted files.

To verify the game files:

  • Launch Steam and go to the Library.

Utilize a Mod Manager, regularly update mods, and carefully follow the correct installation guidelines to avoid issues like SKYUI Error Code 1 in the future. This proactive approach ensures smoother and error-free modding experiences in your Skyrim gameplay.

Utilize a Mod Manager

What does the SkyUI error code 1 mean?

The SkyUI error code 1 means the Skyrim Script Extender (SKSE) has stopped running, which will prevent SkyUI from working correctly. Usually, updating SKSE to the same version of the game will fix the error.

Why is SKSE64 not running SkyUI?

SKSE64 fails to start SkyUI due to an incorrect installation of the SKSE64’s Data folder. You have to place this folder in the main game directory alongside SkyrimSE.exe. Otherwise, the scripts needed for SKSE64 remain undiscoverable by SkyUI.

Is SKSE and SKSE64 the same?

No, SKSE and SKSE64 are not the same. Skyrim Special Edition program functions as a 64-bit application, and SKSE64 was developed with this specific compatibility. On the other hand, SKSE was designed to support Skyrim Legendary Edition (Oldrim), which operates as a 32-bit program.
