Permissions and credits


Use the updated Anniversary files and creations with the old executable automatically, maintaining compatibility with all SKSE plugins like .NET Script Framework.

This project simply contains two launchers. One for the post-AE versions of the executable (Version 1.6+) and one for the pre-AE version (1.5.97).

No dialogues or popups (unless something goes wrong). It just instantly checks the executable is correct and runs the game.

SkyrimSE.exe is backed up automatically with no user input required.

Use the argument -noskse if you want to launch the game without SKSE even if it is detected. 

This has been tested with Mod Organizer 2 and is fully compatible.


Unpack the archive into your root directory containing SkyrimSE.exe

If the main menu is grey, your are on 1.5.97. If it is gold then you are on 1.6+.

To use SKSE:

Install the SKSE files for 1.5.97 normally

Put skse64_loader.exe and skse64_steam_loader.dll for 1.5.97 into the SLL/pre-AE folder

To use SKSE on 1.6+ (additional step):

Put skse64_1_6_xxx.dll into the root directory containing SkyrimSE.exe  

Put skse64_loader.exe and skse64_steam_loader.dll for 1.6+ into the SLL/post-AE folder

Optional (MO2 only)

Add Skyrim Legacy Launcher and Skyrim Anniversary Launcher
