A non-functional SKSe64 is a common error that occurs with multiple users. SKSE64 is the acronym for Skyrim Script Extender 64, a central element of the game’s mod function. Skyrim SE and Special Edition, developed and published by Bethesda Gaming Companies and Softworks, is a successful action RPG.

Among players, Skyrim is a viral video game. But many players also complain about problems with their SKSE64 not working. There are times when it stops working and realizes a mistake has been made. The abbreviation for Skyrim Script Extender 64 would be SKSE64. It is a mod and plays an important role in Skyrim Limited Edition in the application of complex mods. Even if you are using the updated Skyrim SKSE64 model, this problem may occur.

Due to this issue, players cannot start the game after installing the SKSE64 mod binary. The game will occasionally start, but only displays a black screen, so don’t worry if this problem occurs. We will now examine what causes this error and how to correct it.

Causes of this problem

We have studied this problem and created a comprehensive solution guide where most users have registered to solve the problem. We have also investigated the cause of the error and some of the most likely causes are listed below:

  • Firewall – In some situations, the Windows firewall prevents certain parts of the game from communicating with the servers, causing the game to not start properly and mods to not load.
  • Antivirus/Windows Defender – Sometimes in situations where Windows Defender is installed and your computer’s antivirus prevents you from running skse64 or a game. This defender or antivirus marks the application itself as dangerous, as an error message, forcing it to close.
  • Updates – The old skyrim script extension no longer works with the new game, if the game is updated from the game version and the skse64 program must be identical to work together. You can then either update the SKSE version and reset the game version.
  • Faulty mods – This is possible because a certain mod can cause a problem in the game. Usually the old mods didn’t work because the game was changing. After a game update, mod developers usually release updated versions of the mods.

Correct this mistake

Now that you have a basic understanding of the problem, let’s move on to possible solutions. However, in order to ensure that neither solution conflicts with the other, it is recommended to strive for integration of these solutions in the given order.

Corrigendum 1: Granting access to the firewall

In some situations, the Windows firewall may prevent certain parts of the game from communicating with both servers, preventing the game from starting properly. That’s why we’re going to add an exception now instead of a set of window firewalls.

Corrigendum 2: Create a Windows Defender/Antivirus for Skyrim

In some cases, skse64 or the game may stop working with Windows Defender and the antivirus installed on your computer. If false alarm that Windows Defender or Antivirus detects the application as dangerous and stops it. Therefore, at this point we will add another exception to both Windows Defender windows. On this subject:

  • If you meet these conditions, select the file and save the changes.

Corrigendum 3: Create an obsolete version of the software

SKSE64 should also be updated when the game is updated. Because of this, SKSE64 can only work properly with an updated version of the game. However, if you have not yet received an update to SKSE64, you can restore the game to the previous version.

  • You must first open your browser and go to the Steam Database site.
  • Then go to the search bar and type Skyrim and hit the Enter key.
  • You must enter the amount APPID corresponding to the V entry in The Elder Scrolls : Skyrim later.
  • You can now open a new icon and select this number. Users should choose an alternative to the archive on this page.
  • You just noted the number on this new page under the ID heading next to the Skyrim Special Edition exe selection.
  • Then click on this number and the new page will take you there.
  • On this page, you should now select the Manifests option.

Next, note the release before the last published update. If an update was not published six days ago, enter the number given six days earlier.

Then go to your desktop and right-click on the Steam Launcher shortcut and select Properties. You should have entered the console in the Destination field, just after the texts you should have written earlier. You must complete the process without leaving a room. Then click the Apply option and click OK. This applies to the changes you have made. Now use the shortcut to open Steam and select the PlayStation option. In the same option, type download depot (Depot ID no.) (manifest number) and press Enter.

You can see the folder where the old version was downloaded. This is displayed in the console selection. You want to navigate to this file once the download is complete and then locate and copy the executable download. At this point, it should be added to the game’s installation folder. You must select the Copy and Replace option when pasting. Then your game will be reset to the previous version. Run the game now and see if the SKSE64 bug can be fixed or not.

Corrigendum 4: Defective mod.Disable.

Sometimes the problem can also be caused by mods, which then cause this error. Every time the game is updated, it happens, but not the mods. The same mod developers also release updates when a new version is released. However, it can sometimes take some time before an update is released. In this situation, you can disable the same modules that are causing this problem. You should always try to find an update first. If it is not available, disable the add-ons. To disable the mods, please follow the instructions:

  • Start the game by scrolling through the entries and calling up the menu. All you had to do was select the mods in the menu.
  • Then find the mods that are causing problems and disable them.
  • Restart the game and see if the SKSE64 bug is fixed or not.

Corrigendum 5: Restart the computer

Rebooting the computer not only updates the operating system (OS), but also temporarily removes damaged data. This process is considered beneficial in solving software problems.

Frequently Asked Questions

1. How do I get skse64 to Vortex?

Vortex and SKSE64 Vortex Skyrim Script Extender will be a tool used by Skyrim mods to extend the scripting capabilities of the game. This gives customers the opportunity to create an original game with additional features and functions. Users should understand SKSE64 and various related elements before proceeding with the application.

2. How do I know skse64 really works?

  • First make sure that SKSE is working
  • Open the game machine only with (above the tab key).
  • Then try entering the GetSKSE version and press the Enter key while doing so.
  • The SKSE version must be displayed on the console.
  • SKSE doesn’t work any differently, but neither does TESV Acceleration Coating, so you need to check the SKSE installation.
  • Make sure Steam is running before you start the game, and make sure it starts via SKSE loader.exe.

3. Better with the Vortex than with the NMM?

I need to use the mod manager for Nexus. When you add and run a mod, it should automatically reorder your downloaded order to meet the specifications of the download order. However, you can also edit it individually on the Load Sequence tab. Then don’t use it on Nexus models either. I had to import one for Fallout 3 via Google Docs, but it was ready to use because it was a known file format.


Therefore, the problem of a Skse64 launcher or loader not working is very frustrating, because it doesn’t encourage you to play until the problem is solved. To solve the problem as quickly as possible, continue discussing the above solutions and continue your adventure in Skyrim.
