Skyrim Script Extender not Running

Skyrim is on the top in the most appreciated games of all-time list. But, it’s not free from bugs. Gamers have complained that Skyrim script extender not running is one of the menaces that can affect your gaming experience. If you are experiencing a SKSE64 error, then you are not the one who’s facing the issue.

This is a mod tool that plays a significant role in the application of complicated mods on Skyrim. Another concern with the Skyrim script extender not running is that you can’t get rid of the issue even if you have installed the latest version of Skyrim SKSE64. You might be experiencing a black screen due to the Skyrim script extender not running the instance.

Windows Firewall can be responsible for the malfunctioning of the script extender. On the other hand, you might have to deactivate the antivirus software. Or, there can be conflicts among mods.

If you update Skyrim, but not the SKSE, then the Skyrim script extender not running issue might appear. Let’s check how you can overcome this situation with handy solutions.

1. Make changes to Windows Defender or your Antivirus

As complained by a majority of Skyrim users, the computer’s security system might detect Skyrim or any other game as a threat. Whether you have been relying upon Windows Defender or any third-party antivirus software, make sure that it doesn’t consider SKSE64 a threat. It might prevent SKSE64 from running and overall, it can interfere with the game.

Make Skyrim an exception for Windows Defender or any third-party antivirus software. Here’s how you can disable Windows Defender for Skyrim.

  • Press and hold the Windows and I keys at the same time. It will take you to Settings.
  • After that, click the Update & Security section.
  • Check the window’s left pane and go for the Windows Security option.
  • Now, opt for Virus and Threat Protection and click Manage Settings.
  • Locate the heading that says Exclusion, and then you can click on the Folder.
  • You need to add the Skyrim folder to this particular location.

Run the game and see if the Skyrim script extender not running issue still persists or not.

2. Launch SKSE64 as Administrator

Another simple trick that might work for you is to run SKSE64 as an administrator. Here’s how you can run SKSE64 as an administrator:

  • Reach the directory of the game and locate the executable file of SKSE64. Right-click on the file, and after that, go for Properties from the Context menu.
  • Go to the Compatibility tab. Check the box beside ‘Run this program as an administrator’.
  • Then, click Apply followed by OK to save all changes you just made.

3. Toggle Mod Manager Configurations

Users have complained about incorrect Mod Manager settings that might disrupt the normal flow of the game. And, you have to come across a Skyrim script extender not running issue.

You can escape the menace by tweaking a few modifications in the Mod Manager settings. Here are the steps that will help you get rid of Mod conflicts.

  • Explore the Mod Manager. Locate the Settings from the menu appearing on the top of the display.
  • Go to the General tab and check all the boxes under the section named Associations.
  • Select OK, and then, you have to restart the Mod Manager. This will ensure that all the changes have been applied to the settings.

Try launching Skyrim via SKSE, and if the problem is still there, carry on with the next solutions.

4. Deactivate Faulty Mods

If the game has received updates, but the mods remain outdated, then there can be conflicts between the game and the mods. It’s better that your Skyrim game and mods take the same updates at the same time.

If it’s not happening, you should disable all the faulty mods until the particular updates are released from developers. But, try to locate the update for your mods first. If it doesn’t work only then, you can disable the mods in the following way:

  • Open Elder Scrolls and head towards its Menu.
  • After that, you need to opt for Mods.
  • Check the mods carefully and determine which mods are causing the trouble. Select those mods and disable them.

Now, you can restart the game to check if the method has worked. If it doesn’t, then you need to try the next solution.

5. Give the Game Version a Roll-Back

If you can’t fix the update game between Skyrim and its SKSE64, then it becomes impossible to play the game seamlessly. And, you might have to witness the Skyrim script extender not running issue.

Rolling back the current version of the game might help you to get rid of the incompatibility problem.

  • Explore a web browser and reach the Steam database site. Go to the Search field and look for Skyrim. Press the Enter key and locate the Elder Scrolls V: Skyrim.
  • Note down the associated APP ID number and click on it. From the new window, you need to select the option named Depot. After that, you need to note down the section ID number that is located next to Skyrim Special Edition.exe.
  • Select the number, and it will take you to a different page. Click the Manifests option. Check the older number than the latest release date and write it down.
  • Now, go to your desktop and right-click on the shortcut of the Steam launcher. Select the Properties option from the pop-up menu. Go to the Target box and type ‘console’. Make sure that you don’t leave a blank space at the end of the word ‘console’.
  • Save the changes by clicking Apply and OK. Now, open Steam and go to Console. Type ‘download-depot’, and then you have to provide the APP ID number, manifest ID number, or the depot-ID number. Finally, hit the Enter key.
  • Now, go to the folder where you saved the previous version. Check the executable file and copy it. Paste the file in the folder of the game installation.

This will successfully revert Skyrim to its older version. Now, you can try running the game and check if the Skyrim script extender not running warning comes up.


These solutions are enough to recover Skyrim from the Skyrim script extender not running issue. If they don’t work for you, you have to reinstall the Skyrim script extender properly. Go to the official website of Skyrim and install the script extender.
