(I made this because I notice so much user posting on the website their cry for help, what I really do not understand, but I have mercy with the increasingly more victims of the smartphone "click me I think for you“-generation)

 

1) When you download from Steam 1st time Skyrim Special Edition , you get this:

2) You MUST NOT have any other file there in this file structure!

 

2.1)You may verify the version of theSkyrimSE.exeby Windows:

- right mouse click onSkyrimSE.exe => Properties => Details = 1.6.640

 

3)You have somewhere, i.e. in c:\download\ but always OUTSIDE Steam or Windows structure:

FullPatcher_1.6.640.0-1.5.97.0.exe-2022-09-20.exe

or the

BestOfBoth_1.6.640.0-1.5.97.0.exe-2022-09-20.exe

 

4) Do NOT use a Mod Manager ! You click on the exe, that's all.

 

4.1)This Window will open

 

 

if not or if not found “Skyrim Special Edition“ you made something wrong. Stop and begin all new again, after reading and understanding the instruction.

 

4.2) click “Start Patching“ - do not more- some seconds later ...

 

Unfortunately, the text part of that window you cannot expand, but if you mark the text lines und scroll you can read this(it is in reversed order, the last is at top, the first at botton):

 

Finished Patching, enjoy your game!

Dreifels, 2022-12-27 / 2022-12-28

 

Attention! Don't be confused by words of other propagating installation of Skyrim AE:


You MUST NOT  install thecurrentversion  of Unofficial Skyrim Special Edition Patch v. 4.2.8  or another version made after v. 4-2-5b because Arthmoor set dependencies not only to Skyrim game version 1.6.640, but also to the four cc-content esps and by that the downgrade is obsolet.

The more, as that patch has a dependency to 
ccQDRSSE001-SurvivalMode.esl , you'll face another problem: If you load a save made before its installation, the loading is fine. However, if you make then a new save of that older save now after the (forced by Arthmoor) installation the survival mode, you cannot load that new save and ReSaver will tell you that the save is tuncated, no way to repair.

Means: after installing of the survival mode you never again can run a save and char made before. You are forced to start the game total new, all old is lost. This also means: If you want to run survival mod, you cannot run a patch, you have to start new game with AE game version 1.6.640. I found no way to get both working together, yet.


The only proper working patch is the  ''Unofficial Skyrim Special Edition Patch v. 4-2-5b'  which you can find on on Nexus by this path, because Arthmoore set it to delete. He wants to force users to "upgade" to AE.

Update: I found a solution for those users who face the same problem with the survival mod: Go here and read the instruction attached at Skyrim AE Survival Fix

Mabe this will prevent you before the same bug.
