Steam - Cannot Launch Assassin's Creed Origins - Error at hooking API "LdrFindResource_U"

rousseau · 9 July 2026 08:43

I am trying to launch Assassin’s Creed Origins from steam on a plasma system.

However, each time that I attempt to launch the game, steam returns this error :

Error at hooking API "LdrFindResource_U"
Dumping first 32 bytes:

How can I get steam to successfully launch the game ?

According to protondb, the game appears with a Gold rating.

I have tried to launch with the Steam Play compatibility tools below :

Proton Experimental (default)
Proton 11.0
Proton 10.0-4
Proton 9.0-4
Proton 8.0-5
GE-Proton10-34

However, at each launch attempt, I see the same error - the only thing that differs is the list of hex-digits displayed in the third and fourth lines.

Terminal output :

inxi -zv8

I believe you need to run winetricks and install a specific visual C redistributable version, but I am unsure exactly which one. Searching for linux assassin's creed origins "Error at hooking API LdrFindResource_U" should give you some relevant answers.

rousseau · 9 July 2026 13:36

Thanks @bananamangodog, I have to admit that steam, wine and winetricks are all quite new to me, so I apologise if the next couple of questions appear naïve…

As background, I am running steam (for Linux) installed from the multilib repo.

So should I instead install winetricks from the extra repo and then install steam (for Windows) from winetricks and then try to fix the wine prefix with winetricks ?

If so, would that be the “best practice” method to run steam on Manjaro, as the Steam - ArchWiki appears to indicate that steam (for Linux) should be installed from the multilib repo and that a Proton version should be selected from within steam (for Linux) ?

jofi · 9 July 2026 13:47

No from memory winetricks should be available from within Steam for Linux. There must be some advanced or details tab/page for each game where one can do particular settings tor the game. There should be something with winetricks or visual c runtimes.

rousseau · 10 July 2026 02:20

Thanks @jofi, but unless I’m missing something, I don’t see a winetricks configuration option from within steam. I’ve checked all the menus in the game’s properties and I see only the option to select the Proton version.

In any case, I used protontricks from the extra repo to manually install different versions of the Visual C++ runtime (I uninstalled the previously installed version before each new install).

I have tried the runtime versions below, but the same Error at hooking API "LdrFindResource_U" message appears each time I attempt to launch the game.

vcrun2010 (Visual C++ 2010 Libraries)
vcrun2012 (Visual C++ 2012 Libraries)
vcrun2013 (Visual C++ 2013 Libraries)
vcrun2022 (Visual C++ 2015-2022 Libraries, Steam default)

bananamangodog · 10 July 2026 03:55

I’m relatively new to Steam on linux also and I usually keep detailed notes on what I’ve done mostly so I can undo it again if I need to. But I don’t seem to have kept notes on this which makes me think I just followed the archwiki Steam article. I’ve just checked it though and there doesn’t appear to be any mention of winetricks.

I have checked which packages I have installed and are as follows:

Steam from multilib
protontricks from extra (protontricks requires winetricks and pulls it in automatically)
heroic-games-launcher from extra (because it pulls in GE-proton and can make it available in Steam)

From memory you install your game and setup a wineprefix. Then to add the required C++ redistributable you run winetricks (or maybe protontricks - I can’t remember which one I used) which edits that wineprefix environment and allows you to install the C++ redistributable into that environment (I guess its similar to virtual environments in python).

jofi · 10 July 2026 05:21

No sorry i probably confused something. I’ll try to search for it myself when i have time. (I don’t play regularly on Linux. It’s merely a secondary system for things i can’t do on console, and i ran only once into a problem where a game didn’t launch and i had to fix it - but it wasn’t the same error message as yours and i’m also using Heroic for GOG and this even more often than Steam, so maybe it was in Heroic )

Yes, so i confused it with the Heroic games launcher, sorry again. Can’t help with Steam then I think.

mazozo · 10 July 2026 07:57

HI !
Try install Bootle after Ubisosf Connect After it join steam account to ubisoft. Install by Ubisoft Connect.
I play Assassin’s Creed Valhala

rousseau · 10 July 2026 12:21

Welcome to the forum @mazozo and thanks for the suggestion.

I assume that you’re referring to the package bottles ?

If so, I’m not really sure how to manage bottles together with steam, but the error message does indeed seem related to ubisoftconnect - see thread below (same error, different game in same series) :

Therefore, I used protontricks to uninstall the ubisoftconnect that steam had auto-installed by default into the prefix, and then to reinstall ubisoftconnect back into the prefix.

The protontricks version of ubisoftconnect is slightly older than the steam auto-installed default version.

However, the game still fails to launch and the same Error at hooking API "LdrFindResource_U" message still appears.

bananamangodog · 11 July 2026 12:03

Since most reports are that AC Origins works “out of the box” on linux, I’d be inclined to uninstall Steam, etc. Remove the ~/.steam folder, then reboot and start again following the arch wiki guide on installing steam.

The error you’re getting has something to do with overlay hooks, so be sure to disable the steam and ubisoft overlays too (actually try this first).

rousseau · 12 July 2026 06:44

Thanks @bananamangodog. I uninstalled and reinstalled steam, but I still get the same error.

I have disabled the steam overlay, but I can only disable the Ubisoft overlays from within Ubisoft Connect, which does not appear to be launching at all, and which appears to be the cause of the error.

For the record, I have listed below the exact steps followed to uninstall and reinstall steam, to launch the game, and to switch Proton version before relaunching the game.

If anyone feels that there is anything that I have missed, then please let me know.

Uninstall steam and remove its configuration folder :

pamac remove steam
rm -rf ~/.steam

Delete broken simlinks and reboot :

rm ~/.steampath
rm ~/.steampid
reboot

Check that installation pre-requisites from the Steam - ArchWiki ^[1] are met :

reboot

Disable steam overlay within steam :

Steam -> Settings -> In Game -> Disable the steam overlay while in game

Install game within steam (reboot after install complete) :

Library -> Assassin's Creed Origins -> Install

Launch game within steam :

Library -> Assassin's Creed Origins -> Play

Switch Proton version ^[2] within steam and repeat previous step :

Steam -> Settings -> Compatibility -> Set default compatibility tool

The ArchWiki mentions two additional pre-requisites, but these are not relevant : I do not need to add library folders or non steam games, and I do not use Big Picture Mode. ↩︎
I tried all versions listed in the original post ↩︎

bananamangodog · 12 July 2026 09:37

That seems reasonable to me

Perhaps you need to install Uplay/Ubisoft connect manually and link that in steam? Perhaps the following will help. At least then you can disable the overlay first.

Edit: I just found this link which seems to confirm it’s the launcher. Hopefully installing it directly will allow you to run it, update it, and perhaps sign-in (although if you bought the game via Steam signin shouldn’t be necessary).

Edit2:

Also found this which seems related although I don’t know enough about it to work out the fix. I think he ran winetricks renderer=gdi but I don’t know if that’s right or what else it affects.

soundofthunder · 12 July 2026 12:54

@rousseau

This is a Windows error message. You might try updating the vc++ runtimes within the WINEprefix being used.

rousseau · 12 July 2026 15:14

bananamangodog:

Wine fix memo - livelace

Security protection issue:

Error at hooking API "LdrFindResource_U"
Dumping first 32 bytes:
8B FF 55 8B EC 56 8D 45 A0 53 83 C4 80 C7 45 A4
90 8D F7 7B 89 44 24 04 8D 45 B0 89 04 24 E8 5D

the real reason was my ptrace settings:

kernel.yama.ptrace_scope=1 # it works
kernel.yama.ptrace_scope=2 # didn't work

Thanks again @bananamangodog. The link describes two issues and two solutions : the first issue is a near exact replica of the issue that I am encountering so its solution is very promising.

After a few more searches, I found these links, which describe how yama and ptrace_scope are used to define kernel parameters for security.

The ArchWiki link directly above contains this :

The ptrace_scope kernel parameter on my system is set to 3:

cat /proc/sys/kernel/yama/ptrace_scope
3

The Kernel docs describe yama and state that the ptrace_scope parameter can be controlled at runtime via sysctl. In addition, the sysctl - ArchWiki describes how to do this.

I confirmed that the parameter is available to sysctl :

sudo sysctl --all | grep ptrace_scope
kernel.yama.ptrace_scope = 3

I then attempted to temporarily set its value… but there are errors :

LANG=C sudo sysctl kernel.yama.ptrace_scope=1
sysctl: setting key "kernel.yama.ptrace_scope": Invalid argument

sudo su
LANG=C echo "1" > /proc/sys/kernel/yama/ptrace_scope
bash: echo: write error: Invalid argument
exit

How can I temporarily set ptrace_scope to 1 ?

Is there something that I am missing ?

If you or anyone else knows, any help would be greatly appreciated.

Thank you !

@soundofthunder

Thanks, but I already tried to do that with protontricks (see my third post) and incrementally removing and installing different vcrunXXXX variants does not appear to help.

Mod edit: Consecutive posts merged.
If there are no intervening replies, please edit your previous post instead to add further information. Cheers!

bananamangodog · 13 July 2026 03:23

If your ptrace_scope is set to 3 it will require a reboot before it changes (this only occurs with 3 from what I’ve just read). Thus you won’t be able to temporarily set this for running the game if your initial value is 3.

I’ve checked my system and ptrace_scope=1 so I’m not sure why its different (I don’t remember changing mine, and I haven’t documented it so I don’t think I changed it).

I know very little about ptrace so I’ll have to go do some reading, and therefore don’t understand the implications of changing it (or why you’re is set to 3). Hopefully someone else here will understand it better.

rousseau · 13 July 2026 04:05

@bananamangodog

Thanks for all the help and especially for posting the link which pointed towards ptrace_scope.

Yes, that’s exactly what I did

I had previously followed instructions to create + enable a service to set ptrace_scope to 3 :

However, I had completely forgotten about that - I only remembered after I searched for ptrace on the Manjaro forums.

If ptrace_scope is set to 3, then it cannot be changed - this is noted in the second to last line of the yama Kernel Docs (link in my last post). In addition, reboots will not restore the default 1 since the service sets 3 at each reboot.

Therefore, I disabled the service, rebooted, and the default 1 is restored.

The error now disappears and the game launches fine from steam.

Moral of story : I must remember which services I create and enable !

Marking as SOLVED !

bananamangodog · 13 July 2026 04:56

Excellent!

I always keep a folder with notes (markdown files mostly) of any system changes I do so it’s much easier to find issues down the track when you’ve set something once and forgotten sometimes years later.
