This is intended for use with the GOG release, but DRM Free "Just Works" with any version of Skyrim SE.

Bethesda Softworks forced this mod to be removed from Nexus Mods.
Fuck Bethesda Sorftworks, this will be because it can be used without Steam (Cracked), and some dumb lawyer, doesn't realise the GOG release is "Cracked" by Bethesda Games Studios.

I see the "Fixes" have been updated, but that doesn't change the CreationKit.exe though, so we are good to update, but the v3.3 is still available, because I've only tested it runs, not used it.

Current version (Easy Install)
All users put these files in game folder.

SSE Creation Kit-71371-1-6-438-0-1658607602.7Z
Original DRM Free file (for the DIY purists, that prefer to get content from source files).
Original was downloaded as
SSE Creation Kit-71371-1-6-438-0-1658607602.exe
I've renamed that to CreationKit.exe (Required anyway), and put it in this archive, because false positives exist.


All Users
Got Flickering? Nvidia Driver Issue, update to latest Drivers to fix.

MO Users Only
You MUST run CK from within MO to see MO Mods, add as executable, should auto happen, but if not you can click the Gears Icon to set it manually.

Note: you may need to manually remove the SteamID, to stop Steam launching
Pretty sure MO, does that, being too "Helpful". We don't want Steam running though.

MO Users will still get told CreationKit.exe requires Steam to run.
IT DOES NOT (When DRM free)
Tell it to run CK without Steam, and to remove the nag screen, select Always Do this for CreationKit.exe from the ddropdown choices.

If any of that sounds to complicated, WTF do you want the CK for, download mods made for you instead.
MO isn't for you, it is an advanced mod manager.
That means you must be willing to RTFM (Read The Fucking Manual).
If you want "It Just Works", stick with Vanilla, Todd Howard wouldn't "Just" lie would he?
