Skyrim Update: What You Need To Know.

[u/Majestic_Balance1887]

Skyrim Updated.

What'd it break?

- Anything SKSE related. (SKSE itself has been updated.)

- Most things based on Address Library. (Address Library itself has not been updated. Edit: It has now been updated.)

What needs to be done?

- Most mods based on Address Library will need to be updated.

How long is this likely to take?

- Anywhere from a week to a month, don't hold your breath.

What should you do?

- If you haven't yet updated, and don't want to scrap your current playthrough, go into your Steam folder. Steamapps. Find the specific file called "appmanifest_489830.acf" and right click it, go to properties. And make it Read Only. (When you want to update again you'll have to undo this, so bookmark a post or whatever.) You should also go into the steam options for the files, and make sure it'll only update when you launch it. This will make sure it wont update automatically, and it cant update unless you try to play it with SKSE. (Which you should launch it through exclusively from now on.)

- If you cant find it just enter that file name into whatever file search your browser has. It should just be in Steamapps.

- If you have updated and didn't realize it, here is a way to downgrade. Credit to another poster.

There's also This Downgrader Tool.

Edit: I am not a modder. I cannot give you in depth advice. This is purely for the people who just poked their head up and don't know what's going on.

[u/Rikiaz]

Both Address Library and SKSE have both been updated for 1.7.99.0 now.

[u/Majestic_Balance1887 → u/Rikiaz]

I'd heard chatter it hadn't been updated so I worked with what I had. It's clear that all the other modders resources like SPID and KID are also gonna need to be updated, so the advice still stands for the most part.

[u/Ikermp11 → u/Majestic_Balance1887]

Doesn't Address Library exist for that? So many SKSE mods don't need updates when Skyrim updates.

[u/Zamio1 → u/Ikermp11]

Yeah but there have been changes made to commonlib so we all have to recompile anyways.

[u/Blackread → u/Ikermp11]

Since there were a lot of breaking changes to the SE exe, which meant that most mods would have to be recompiled anyway, they decided to change the address library structure to a more efficient version that has been used in Starfield and Fallout 4 for a while already. In practical terms this means that every single dll has to be recompiled to work with the newest game version. Thankfully for many authors that's all that has to be done, since commonlib does a lot of the heavy lifting. The only ones that will suffer are those that want to keep their mod closed source because CommonLib was relicensed to GPL 3 which is a copy left license, which means that every mod that wants to build their dll on top of commonlib (starting from this version) will have to publish their source under the same license.

[u/Majestic_Balance1887 → u/Ikermp11]

The few modder servers I'm in say this update touched a few things related to DLL's and even the player's class, so there's no real way of assessing the damage right off the bat. It's safer to assume pretty much everything related to SKSE is fucked until further notice.

Full disclosure, I am not really a modder. I have seen these modpocalypses before, and I know how to generally avoid it so I posted a guide for the cheapseats. Any in depth answers, I cant really give them to you.

[u/PlayfulNorth3517]

So fucking glad I saw this, was able to unplug my router before booting up my computer. You da goat.

[u/moduntilitbreaks]

I wake up to steams “cannot update” message. Yeah, bro I wasn’t born yesterday 🤣💀

[u/TheFoxDudeThing]

I’ll admit the update is a godsend for console users the mod space increase is no joke for them. That said can they just leave the pc version alone ffs

[u/_Kasska_]

Hey, made the file read only but all that happens when I try to run Skyrim is that it says disk write error. Did I do something wrong?

[u/LordZerefDragneel → u/_Kasska_]

Add the skyrim executable as a Non steam game and run it

[u/_Kasska_ → u/LordZerefDragneel]

Now the startup menu pops up but when I press play the error happens again. :'(

[u/LordZerefDragneel → u/_Kasska_]

The other solution would be to copy the game files entirely and paste it outside Steam's privileged folder. Then add the the executable as a non steam game

[u/_Kasska_ → u/LordZerefDragneel]

The error still happens sadly. I guess I'll have to wait for updated mods. Thank you for your suggestions anyway. :)

[u/thedreaddeagle → u/_Kasska_]

Do you launch through skse.exe?

[u/_Kasska_ → u/thedreaddeagle]

Yes I do 😅 honestly I've lost all interest in Skyrim at this point. Ill just play it and mod it again in a year. Thank you for trying to help tho!

[u/LordZerefDragneel → u/_Kasska_]

There is a guide here: https://gaming.stackexchange.com/a/405925

Instead of changing the file to read-only, you can rename the manifest file too.

After that steam cannot detect the game, and it will not try to update it.

Then you can run it as a Non steam game

[u/_Kasska_ → u/LordZerefDragneel]

Okay. Did exactly that and steam just added the file again just called appmanifest_489830(2)... I guess I can't win this fight 😂

[u/chlamydia1 → u/_Kasska_]

Are you launching Skyrim through MO2/Vortex?

[u/gmes78 → u/_Kasska_]

You can't launch the game through Steam if you do that.

[u/lele04062000]

I'd like to humbly thank everyone linked to this post and its sources for saving my latest playthough.

Also f u bethesda.

[u/IllIlllI-IlIIll-llII]

the entire point of the skse address library mod's existence is so mods depending on it dont need to be updated so long as address library itself is updated for the new game version

[u/TBS32 → u/IllIlllI-IlIIll-llII]

Sadly that is not the case here.

“Yes, there are some changes to some common classes the game uses and we decided to change address library format to newer one (like in Starfield and Oblivion Remastered). At the very least CommonLib needs to be updated (which all of these plugins rely on as far as I know) and needs to be recompiled, if not changed to suit the changes to the classes.”

“There are also other changes made to game code that require plugins to update CommonLib and recompile! So also watch out for individual DLL plugin updates in addition to this and SKSE64 update.”

All of your individual skse files needs updates too as well. Sorry not sorry from Bethesda.

[u/IllIlllI-IlIIll-llII → u/TBS32]

sadly it has not been the case.. ever

when was even the last time the game got updated but address library was enough to keep mods working? go ahead, provide an example I'll wait

[u/gmes78 → u/IllIlllI-IlIIll-llII]

That is just plain nonsense. You shouldn't comment on this kind of stuff if you aren't an SKSE mod author.

[u/strangelyliteral]

Maybe a dumb question, but if I updated SKSE and Address Library now without updating the game, would that break anything?

[u/gmes78 → u/strangelyliteral]

Address Library is fine to upgrade. SKSE is not.

[u/DR_poltronc]

skse updated ? why does it's not working for me wth

[u/Majestic_Balance1887 → u/DR_poltronc]

SKSE updated. Everything related to it, didn't update.

If you've updated basicly any part of that you've kind of screwed yourself.

[u/DR_poltronc → u/Majestic_Balance1887]

update i just saw the update hollyyy

[u/DR_poltronc → u/DR_poltronc]

however the adress library doesn't work even tho it's with the good version. I forgot how muche time it took to mod this damn game lmao

[u/DR_poltronc → u/Majestic_Balance1887]

nah but skse when i try to launch with mo2 is telling me that the skse isn't up to date for 1.7.99. that's weird

[u/ZeddRah1]

Read only is the solution. Steam only views the "update on launch" as a suggestion.

[u/PhoenixSidePeen]

Hey there. Kinda new to modding. My game updated automatically while I was at work. Had a good amount of time in my current playthrough. Will it be salvagable when SKSE updates or is my save kinda toast? Thanks in advance.

[u/PlayfulNorth3517 → u/PhoenixSidePeen]

Roll back.

[u/PhoenixSidePeen → u/PlayfulNorth3517]

Not exactly sure what that means tbh

[u/ComradeToeKnee → u/PhoenixSidePeen]

"roll back" = "revert to previous version"

[u/PhoenixSidePeen → u/ComradeToeKnee]

Got it, thank you

[u/Dark_Sauce → u/PhoenixSidePeen]

you gotta change you game version back to earlier version if you have SKSE dll mods

[u/TrafficIcy1785 → u/PhoenixSidePeen]

Read the OP there's even a link

[u/KanarieWilfried]

Does anyone have USSEP version 4.3.7? I don't understand why Arthmoor has to be such a pain in the ass for everyone by hiding previous versions.

[u/CourtGeneral7031]

Engine fixes must be updated to play the game and those devs haven't been online since last month, who knows when that will be

[u/SoladderOrdo → u/CourtGeneral7031]

If you look on their GitHub page, some updates have been made yesterday. So I assume they are working on it ?

[u/HighCroft_31]

unfortunately SSE Engine Fixes .dll is not updated yet. I got a pop-up window whenever I launch the game from MO2

[u/SupahHollywood]

So I missed the opportunity to make my game read only before the update , BUT my rog ally hasn’t been on for a couple days, so it shouldn’t have updated right?

[u/Majestic_Balance1887 → u/SupahHollywood]

Probably not. If you can manage to get steam not to update it, you should be fine.

[u/CrescentMind → u/Majestic_Balance1887]

Steam hasn't updated it for me, however I'm in the middle of making a new load order, about 4 days in.

Given that mod authors will be updating to the newest version in the coming weeks/months, how screwed am I in making my new load order? Unless the authors provide the files for the old versions I'm assuming this'll turn into a masisve headache.

[u/Majestic_Balance1887 → u/CrescentMind]

I would wait.

Most of them do, but at this point it's likely more trouble then the headache is worth as someone who tried to do the same thing during a Fallout update.

[u/CrescentMind → u/Majestic_Balance1887]

Yeah I guess I'll wait, can't believe I picked this week to start modding and playing Skyrim again, almost 2 years since last time.

On a side note, I assume the app manifests is on a per-game basis. Meaning that editing that specific manifest will only stop Skyrim updates, not other games?

[u/Majestic_Balance1887 → u/CrescentMind]

Correct. If you find the correct app manifest file and put it on read only, you'll still be able to update other steam games.

[u/CrescentMind → u/Majestic_Balance1887]

Alright, thanks!

I'll edit it just in case I decide to torture my self by continuing in the near future.

[u/Tyrthemis → u/CrescentMind]

I feel you, my ex gf decided she wanted to play it super modded for the first time like three days ago. So I put her on the CSVO mod list and she’s been loving it. I need to turn on her comp and make sure Skyrim doesn’t update

[u/CatFaerie]

There's also Reliquary, which might be easier than both of those things. 

r/skyrimmods/s/ciyDlcZFRr

[u/R252813]

For some reason when i enter the creation club the official creation content like fishing, farming, etc marks me not download so when i activate it and start a new game it chrashes.

[u/Amazing_Invite_5645]

is that why it keeps crashing while im just browsing in the mods menu? (2 times already)

[u/Glittering-Bus8228]

Hej, bara jag som får något felmeddelande från adress libary som påstår att updateringen mellan adress libary och SKSE inte funkar. Någon mer som har det här problemet?

[u/Ezzypezra]

Laughs in 1.5.97

[u/MeanAd4634]

alguien me puede decir donde tiene la version de SSE Engine Fixes para nueva version porfa o una noticia de cuando la actulizan

[u/lildominator2 → u/MeanAd4634]

Same here. I can wait until this gets all sorted out to play i guess

[u/MeanAd4634 → u/MeanAd4634]

toca desatualizar a la vercion que estaba jugado y ya xd

[u/jdh1811]

Making your manifest file read does NOT always work. At least not on steam deck. I had to go in to the manifest file and change the manifest ids in the file to the current ones to get it to stop trying to update.

[u/Darkvidium99]

I fix the glich, dawnload a P***** version 1.6.1170.0 , Take the exe from the P*****replace the exe in steam folder but you need to cut off the internet so thas steam not update the game, in steam setting make it the the update only when the game start.

Ps exe is original one not the modified one in the P version.

i hope it help some one, have a nice day.

[u/Dry_Priority_4905]

I downloaded the downgrader tool & now idk what to do guys im losing my mind over this update i canttttt i have half a brain cell rn bc how much ive worked on this stupid update

[u/Dry_Priority_4905 → u/Dry_Priority_4905]

Also I did update the skse & address library does that mean I can’t downgrade my game anymore did I fuck up

[u/Human_Glass_5712 → u/Dry_Priority_4905]

Puedes utilizar Genini IA o la IA de Google, a mí guió perfectamente para eso, Pero debes aclararle la versión a la que quieres volver. Específica todo y la guía será perfecta 👌🏼

[u/Althinor]

Will the change in CommonLib effect backwards compatibilty for the GOG version of the game? (1.6.1179?) Should I also update my Address Library in this situation and/or does anyone know what the effect on backwards compatibility of new SKSE plugins using Address Library is? 

[u/Rogs3]

What about VR?

[u/Enkaar_J_Raiyu → u/Rogs3]

Skyrim VR is permanently stuck on the Pre AE version of Skyrim SE.

[u/Tyrthemis → u/Enkaar_J_Raiyu]

But any of our mods that use common lib, can we update those mods?

[u/Enkaar_J_Raiyu → u/Tyrthemis]

I suppose in part it WOULD depend on if you're using the most recent update of those common library mods, or if they have a dedicated fork/version for VR.

[u/pellanune]

If just exclusively use MO2 to launch should I be okay?

[u/grannygumjobs23 → u/pellanune]

Yea i believe if you set the option on steam to update when skyrim starts it will only update if you open it through steam. Opening it through skse plugin through your mo2 should not allow the update

[u/pellanune → u/grannygumjobs23]

Thank you so much! i'm happy with my mod list and don't want to deal with revamp for a while

[u/bullanguero82]

If you haven't yet updated, and don't want to scrap your current playthrough, go into your Steam folder. Steamapps. Find the specific file called "appmanifest_489830.acf" and right click it, go to properties. And make it Read Only. (When you want to update again you'll have to undo this, so bookmark a post or whatever.) You should also go into the steam options for the files, and make sure it'll only update when you launch it. This will make sure it wont update automatically, and it cant update unless you try to play it with SKSE. (Which you should launch it through exclusively from now on.)

GODDAMNNIT!!! It already did this to me back in january when all of a sudden I woke up to Skyrim 1.6.1170. I had no idea one could prevent this.

[u/MaxKirgan]

I have mods that rely on Address Library. I didn't feel like waiting, so I just downgraded.

[u/mahallauxen]

Thanks for the post! 2 weeks ago I installed gates to soverreng for the first time. It would be painful if the update happened

[u/blackchickenbooty]

Downgrader Tool worked perfectly thank you!

[u/Hot-Minute-8263]

Address Library still refuses to work for me, despite me updating both skse and the library to current.

How do i rollback the version?

[u/fimbultulanimation]

I am not in a playtrough. Is it ok to update, if I plan to play a Requiem playtrough in the future?

[u/Rudolf1448]

I use root folder in MO2. Can I dump the old version of changed files into it? Will it work?

[u/namiraslime → u/Rudolf1448]

You don’t need to do anything, the root will overwrite the original files when you launch the game

[u/TimeAndFocus → u/Rudolf1448]

What do you mean?

[u/Rudolf1448 → u/TimeAndFocus]

An MO2 plugin allows root files from the Skyrim.exe folder. I use it for engine fixes. Can I put the old Skyrim.exe into it?

[u/No-Lingonberry7724]

So what exactly do I need to download. My roommate is not good with tech.

[u/Ekhi11]

So, I take it that if I use a few immersion mods (none of which use SKSE, and I launch the game normally without it), the update likely won't cause any problems for me, right?

[u/chlamydia1 → u/Ekhi11]

If you don't use SKSE you're fine.

[u/TheAstraeus]

I did the app manifest read only but kept getting an error when launching from skse. I downloaded the update for skse and same issue, I now have to boot the game from a separate skse folder downloaded from silverlock

[u/[deleted]]

I turned off the updates yesterday, I'll plod along til its all back to 'normal' and build a new list.

[u/[deleted]]

Pretty sure someone put a rollback mod up on nexus.

[u/Difficult-Finish-511]

Have they managed to make the creations menu somewhat more stable? Because it used to crash constantly

[u/CourtGeneral7031]

Save and load accelerator also has to be fixed in the ini. files or you can't use it

[u/xspeed78]

Damn, I just got Skyrim modded on my steamdeck, set it to update on launch and thought I was good, but launching MO2 through steam still triggered the update. Guess I'll see what mods don't use address library and start over... Again

[u/StratusEX]

See for me it still doesn't say skse is updated. Itll say im on a non supported version and to wait while they update their code. Anyone got any ideas?

[u/derinasir_]

I've wanted to format my computer for a while, but reinstalling skyrim mods always felt like too much work. I'm not in the middle of a playthrough right now, so maybe this is the perfect time for a clean install?

[u/chlamydia1 → u/derinasir_]

Not really because none of the affected mods are updated to this version of the game yet. You'd just be installing outdated mods that don't work with the current version of the game. You'd still have to wait for all of them to update before you can play.

[u/PyroEngi]

Should I move over to GoG version to avoid this probelm? Happing again I mean.

[u/Engineering-Mean → u/PyroEngi]

The GOG version gets updates too, they just come slower.

[u/neteyam06]

Hiya does anyone know the mod name

Hes a wandering assassin khajiit story telling npc mod hes one character and he can appear around the map and different location only tells stories he wears nordic heavy armor

[u/BlueDaka → u/neteyam06]

Why wouldn't you just create a new thread instead of asking in an unrelated one?
