Key facts

• Purpose: Extends Papyrus scripting with new functions, events, and native hooks mods rely on.
• Compatibility: Must match the game executable build (SkyrimSE.exe) — SKSE plugins built for 1.1.47 only work with that runtime.
• Components:
  • skse64_1_5_97.dll (loader/runtime hooks) — names vary by build
  • skse64_steam_loader.exe / skse64_loader.exe (launcher)
  • Data\SKSE\ plugins/ scripts (for mods)

What is "1147"?

• Runtime 1.1.47.0 (shortened to 1147) = Skyrim Special Edition (SSE) 1.5.97
• This is the last pre-Anniversary Edition build of Skyrim (released Nov 11, 2021).
• This version is still used by thousands of modders because many complex mods (requiring .NET Script Framework, No Grass in Objects, etc.) never updated to AE.
