Skyrim AE downgrade guide

Step-by-Step Guide to use the all new Creations while still playing on SE (1.5.97)
Method A) .exe swap (use new .esm and .bsa files)
1: BACK UP YOUR SKYRIMSE.EXE AND BINKW64.DLL
2: Update the game to AE (1.6.318) -> Download any creation you want, or all of them.
3: Copy the SkyrimSE.exe and Binkw64.dll back into the folder: remove Bink2w64.dll from the skyrim directory.
4: Install ANY mod that replaces the main menu, be it Cleaned Main Menu, NordicUI, Main Menu Reshaped, etc; This is to avoid a bug where upon failing login on Bethesda servers your character is unable to move.
5: If you had Unofficial Skyrim Creation Club Patch installed, uninstall it. The Updated CC filed were fixed; remove any mods that change quests from the CC, stuff like Knight of the North or On a crimson trail.
6: Make sure you don't have a file named 'Patch.bsa', if you have it, delete it.

Method B) Download Ayyyylied ruin texture set
1) Kept 1.5.97 everything (.esm, .bsa, etc); basically don't update at all.
2) Download all of the CC, either place it on \Data or pack it for MO2.
3) Download and install with MO2: https://mega.nz/file/SM1wVYjD#lLCKxZ5j4Et_CA86F_zN_4yoTOrXt24KBcAZzFoQqi4 (Ayyyleid texture set)
4) Download FishLogo.png and make the following folder: data\textures\interface\books\FishLogo.png (picrel); rename Data to Fishing_Logo and put it on MO2\Mod, activate.
5) Play.

Congrats, you can use all your SKSE mods while enjoying the new CC content!
