So, in order to run any scripts or commands that follow, make sure you're running as an Administrator. Unfortunately, you can only create Symbolic Links as an admin in Windows. If you make a symbolic link at My Games\Skyrim that has My Games\Enderal as a target, every file that is read or written to My Games\Skyrim will end up at My Games\Enderal instead. These are like shortcuts, but they're followed automatically by any program without any extra logic. The SKSE version that comes with Enderal doesn't support the current version of the Creation Kit, so you cannot run the CK through SKSE to use the SkyrimRedirector plugin to redirect those files. Additionally, it is hardcoded to look for Documents\My Games\Skyrim.ini and Documents\My Games\SkyrimPrefs.ini, which Enderal doesn't use. The Creation Kit can only be executed from the steamapps\common\Steam folder. Optionally, extract the 'E - Scripts.bsa' archive to your Data folder to make scripts editable.Replace SkyrimEditor.ini on your Enderal folder with the one from the zip.Download and unzip the QuickFix.zip attachment.Uninstall the Creation Kit if you already have it installed.This post will teach you why and how to fix it.
The Creation Kit doesn't work by default with Enderal.
