Steam updated SkyrimSE after a win11upd and broke everything (FIXED)

[darkfender666]

FIXED look below for solution and HOW to prevent steam to update the game by itself after a steam anticheat error (caused by win update)

 

 

Time ago a framework update completely broke my oldrim.

 

Took a month to rebuild it with anniversary edition and worked for couple months 

 

Once again yesterday a new windows framework update broke my skyrimSE

 

error launching SKSE STEAM AE: (i surely had SKYRIM updates disabled)

--------

You are using a newer version of Skyrim than this version of SKSE64 supports.
If this version just came out, please be patient while we update our code.
In the meantime, please check http://skse.silverlock.org for updates.
Do not email about this!
Runtime: 1.7.104
SKSE64: 2.2.6

--------

 

so i updated skse 

 

Error changed saying address library version was wrong

So installed address library and all skse dependeincies

 

 

A popup appears saying  Skyrim REL/ID.h  failed to load address library file.

 

 

SSEDIT does not give any error.

 

Please help

 

Last files downloaded and installed....maybe i am missing something...

This is the load order (with LOOT)

Go to GOG.com and buy Skyrim AE it does not need updates. The reason behind it it has a different engine it's a offline version so it has different software engine then steam variant no updates need.

Did not work.

 

Basically i noticed every single mod using address library stopped working

 

each one gives that message

I can disable few but basically every single mod using address library won t work until they release an update... that sucks so bad.

UPDATE:

I think i fixed everything

 

for people that might have the same issue:

Made an update in win 11

Steam gave an error at restart about some anticheat....

restarted

Steam updated game to 1,7,X silently (i think)

 

 

Upgrading skse and address library did not work: every mod using AL gave errors.

 

So i downloaded reliquary app an app that lets you downgrade Skyrim (there is a Youtube vid on how to use it)

-problem: i installed manually skse (only one i had to install manually):

-had to delete skse loader the dll and changed name to the folder "SRC" under game files folder

-at this point i installed SKSE (manaually again), and then with vortex, all mods related (i had uninstalled to try the upgrade): SKSE engine fixes files etc and all 1.6 address library files.

 

Everything works.

 

Next step taking away steam privileges to update skyrim:

 

I shut down skyrim and STEAM

 

I went to

C:\Program Files (x86)\Steam\steamapps\

looked for 

appmanifest_489830.acf

 

Right click=> read only => ok

 

this should prevent skyrim to update the game no matter what (also remember to choose the option update only when game is launched in steam for skyrim but with read only it sould not matter)
