📋 About This Mod

What it does?

Allows preload F4SE plugins before the game initializes.

Do I need this and is there any benefit to this?

No! You don't need this unless a mod specifically says you require this. There is no benefit to having this for no reason. At the time of writing, you only need this if you are using PrivateProfileRedirector F4 or Buffout 4. There is no other reason to use the preloader otherwise. It allows the mod to make edit to the game code before the game has any chance to run that code.

NOTE: Starting with Fallout 4 NG update, F4SE plugins can opt in to use the preload method built in the new F4SE releases (F4SEPlugin_Preload export function). Refer to the description of the F4SE mod you're installing to make sure you really need this preloader.

How does it work?

Library WinHTTP.dll is loaded by game automatically, which preloads the plugins, then redirects all function calls to the original WinHTTP.dll file in your system directory.

Installation

Put WinHTTP.dll and xSE PluginPreloader.xml in your root Fallout 4 directory (where Fallout4.exe is), NOT in the Data folder. If you're using F4SE, make sure to run it with -forcesteamloader command line option.

Uninstallation

Delete installed files from your game folder. Any mod that depends on this will cease to work correctly.

Configuration

Preloader is implemented as proxy to WinHTTP.dll and thus is incompatible with any mod that changes this DLL (none I found). In such case you need to rename another mod's WinHTTP.dll to something else and specify new real DLL in xSE PluginPreloader.xml file. Refer to the XML file for more detailed instructions.

ATTENTION!

Go to the xSE PluginPreloader.xml file and change the load method to OnThreadAttach or

OnProcessAttach

 if the default doesn't work.

- If you're using Vortex to install mods use the Engine Injector install method (DINPUT for older Vortex versions) for this mod.

To change the load method, edit the value of the "Name" attribute in the XML file.

<LoadMethod Name="ImportAddressHook">

</LoadMethod>

For example, if you need to set it to "OnThreadAttach" or "ImportAddressHook" edit this section like this.

<LoadMethod Name="OnThreadAttach">

</LoadMethod>[/co

📊 Pros & Cons

✅ Pros

  • Essential for mods that need to hook early—this is the backbone of many advanced F4SE plugins.
  • Massive adoption (34k endorsements, 3.2M downloads) means it's battle-tested and community-approved.
  • Still updated in 2026, so you're not installing a dead mod that breaks your load order.

⚠️ Cons

  • Requires F4SE to be installed first—if you're new to modding, that's an extra step.
  • No detailed documentation in the description, so you'll need to rely on mod pages that reference it.
  • If you don't use F4SE plugins that need preloading, this mod does nothing for you—it's purely a dependency.
🎯 Is This For You?
For Fallout 4 modders who run F4SE-dependent mods that require early loading, like certain framework or utility mods. If you're a casual player using only basic mods, you can skip this. But if you're diving into advanced modding, this is a must-have foundation.

💡 Beginner Tips

  • Make sure F4SE is installed and working before adding this—test with a simple F4SE mod first.
  • Place the plugin preloader files in your Fallout 4 root folder, not the Data folder, to ensure it loads correctly.
  • Check the mod's comments section for any known conflicts with specific F4SE plugins, as some may require specific versions.
