Unofficial Skyrim Special Edition Downgrade Patcher

THIS MOD HAS BEEN DISCONTINUED - Please use Reliquary instead

This utility will back-patch the changes to your game made by the Anniversary Edition of Skyrim. It will take an up-to-date Skyrim SE install or a Skyrim AE install and patch the executables back to their 1. 5. 97 versions. Note, this utility works via binary patching the new files back to the old files. This means you need the correct game state and patcher for these to function.

If, however, you just want to download a clean copy of the game, and are okay with connecting an app to Steam, please check out my other mod which I feel is a lot simpler. Either way, the choice is your's

After patching you should be able to use SKSE, ENBs, and all your favorite plugins without issue.

Instructions:

Download the patcher of choice, select your game folder, and let the app do the rest

Types of Patchers:

Some of the included patchers will downgrade from one version of AE to another, while others will download the full game to Skyrim SE, make sure you have the right patcher for what you are trying to do.

Q: It says a file is in the wrong format!

A: This is either because you edited a game file, or chose the wrong patcher. Verify your files via Steam or try again.

Q: How do I run this in Vortex/MO2

A: Don't. Run it outside of any mod managers.

Q: Why am I at verison 1. 0. 0. 0 after using this?

A: You're not, you're looking at the wrong version number

Q: I used the "Best of Both Worlds" Patcher and now I can't move with the keyboard, or in the menus!

A: There's a strange conflict with this patcher and lightly modded setups, I recommend some sort of main menu replacer like Clean Menu to override these files and fix the issue.

Q: I have a bug, where to I submit a report?

A: Due to the amount of traffic this mod receives I need a proper bug tracking system, so please submit bugs on the Github page

Q: There's an error about something named "api-ms-win-core-winrtl1-1-0.dll"?

A: This app only supports Windows 8+, Windows 7 has been end-of-life for over a year, and Windows 10 is a free upgrade.

Q: Does this work with a non-English version of the game?

A: Not currently, feel free to submit a PR on github though

Q: I got the game via the Xbox subscription

A: Then it doesn't work with SKSE and you don't need this

Q: I didn't get this game via Steam or Xbox subscription

A: Then go buy it on steam, and don't pirate the game
