Skyrim is a very popular video-game among gamers. But often it is reported by many gamers that they are facing the problem with their SKSE64 not working. There are times when it stops working and shows an error. SKSE64 is the abbreviation for “Skyrim Script Extender 64”. It is a modding tool and plays a crucial role in applying complex mods on the Skyrim Special Edition. 

You will face this problem even when you are using a newer version of Skyrim SKSE64. Due to this problem, the gamers become unsuccessful in launching the game after installing the SKSE64 executable mods.

Reason for Which SKSE64 Not Working Error Occurs:

So, here are the primary reasons that are responsible for this error to show up:-

  • One of the primary reasons for this error to occur is the Firewalls present in Windows. These prevent some of the gaming elements from connecting with the server. Due to this reason, the game is unable to launch properly. 
  • Another reason for this error to occur is due to the antivirus software installed in your Windows, or due to your Windows Defender. This software can prevent the game or block the ske64 from running. This is because sometimes it identifies the game as a threat. 
  • When you update the game of Skyrim, then the old SKSE will not work. In order to work properly, you have to update it as well or you can roll back the game to its previous version.  
  • However, this error can also occur because the Mods that you have installed are causing the problem. Generally, when you update the game, the Mods will not work. Thus, to work them properly, you have to update the Mods as well.

Fix 3. Make the Version of the Game to RollBack

When the game receives an update, the SKSE64 also gets an update. This will allow the SKSE64 to work properly with the updated version of the game. However, if the SKSE64 has not yet received an update, then you can roll back the game to its previous version. 

  • First, you have to open your browser and go to the Steam Database site. 
  • After that, go to the search bar and type “Skyrim” and hit Enter.

  • Now, within this page, you have to select the “Manifests” option. 
  • Next, you have to write the number down which is older than the last released update. Eg, if the update was released 6 days ago, you have to write the number that was listed before 6 days. 

After that, go to the desktop and right-click on the shortcut of “Steam launcher” and click on the “Properties” option. In the “Target” box, you have to type “console” after the texts that were written earlier. You have to end by leaving no space. Then, click on the “Apply” option and then “OK”. This will apply the changes that you have made. 

Now, open Steam by using the shortcut and then select the “Console” option. Within this option, you have to write “download-depot (App ID number (Depot ID number) (manifest id number)” and hit Enter. 

You will be able to see the folder in which the download of the older version is being done. This will be displayed on the “Console” option. After the completion of the download, you have to go to that folder and then locate the executable download and copy it. 

Now, paste it in the folder for the game installation. While pasting, you have to select the “Copy and Replace” option. After this, your game will go back to the previous version.

Sometimes, the mods may cause a problem and that will generate this error. This happens when the game has been updated, but the mods have not. When an update for a game is released, the developers of the mods also release the updates. However, sometimes the update may take some time to be released. In that case, you can disable the mods which are causing the problem.
