Thank you for writing this script and sharing it. I do have one question about it. On the last two lines, do you intentionally swap the archs and the dirs used? Didn’t make sense to me, so I wanted to change it. Figured I’d check first.

replace_dlls $AOE4_WIN_SYS32_DIR x64 replace_dlls $AOE4_WIN_SYS64_DIR x86

Sys32 is actually for 64bit and sys64 is for 32bit. It's super confusing but you can look it up online and read more about it.

https://download.microsoft.com/download/9/3/F/93FCF1E7-E6A4-478B-96E7-D4B285925B00/vc_redist.$arch.exe, this link that you are using with wget is empty, can you just name the file?

@Farzam003 Ma5onic posted them above at the end of his detailed explanation

Hey guys! I'm pulling my hair out over here. Total beginner for Linux, deck, and scripts. I've read all the comments, they've been super helpful. In my early attempts, I think I screwed something up and now the game crashes when the multiplayer game is just about to begin. So yeah, I made it worse.

Any help would be appreciated. A few questions I have:

How can I restore things back to normal so it doesn't crash immediately?

What Proton version should I be running it on?

Do I need to change anything about the "STEAM_DIR=" path?

Thanks in advance, and thanks for making the workaround.

One of the few games not working on Garuda Linux

As I'm reading this, I became involved with trying to fix this issue for a friend who has a Steam Deck so I can play multiplayer with him so I want ask for some answers on the following questions:

1. Does this method and script still work in the latest update?

2. Is there anything else I should do further from those 4 steps before booting the game?

3. Does the script run by itself with those applications installed and those redist files downloaded when booting the game because you didn't mention running the script in those steps?

My friend was following the steps on the github page with the script but it was too confusing, gave him a headache and didn't get it to work. Even I was trying to help over a discord call but those script steps were confusing as well and hoping your steps are more clearer and simplest explanation. I'm not an expert on Steamdeck navigation because I haven't really fiddled around with it in my hands but I am experienced with using a PC and navigating on that.

Please help! Thanks!

@Yohomie99 I'm not playing this on my steam deck, so I don't know if there happens to be any thing different but, my intuition says it should be the same.

1. I ran this script back in season 2, and have not needed to run it again since. I was able to play some games a couple days ago.
2. Not that I'm aware of
3. I'm not sure what you mean here. Scripts don't execute themselves. It sounds like you guys are trying to execute these lines one by one by yourselves? You want to download this file, or copy and paste it into a file, and then execute the entire script at once.

@FoxMulder24 sorry to see that you haven't had a response. Hopefully you were able to get it to work. You can always do a 'reset' by uninstalling and reinstalling the game from steam.

@broaken13 I appreciate the reply! I did end up finally stumbling my way into getting it to work. I learned a ton about Linux and was reminded of the old Edisom quote: "I have not failed. I've just found 10,000 ways that [the AoE4 multiplayer fix] won't work." Oddly specific, but accurate!

@Yohomie99 , I can confirm at least that once I got everything right, the script ran and I never had to run it again.

Yes so this script "aoe4-mp-fix-sh", what do I do with it when I've downloaded that because those 4 steps didn't mention it?

But the previous comment mentioned downloading the script in Step 2 but I didn't understand what step 3 and 4 means:

@jm-chase I don't have a Steam Deck but the commands are below:

1. install aoe4
2. download aoe4-mp-fix.sh
3. chmod +x aoe4-mp-fix.sh
4. ./aoe4-mp-fix.sh

This is why I wondered if there are steps or I just simply download the script itself and then follow @Ma5onic 4 steps.

@Yohomie99 I posted a how to thread over on Reddit, trying to break it down into easier steps. It is not perfect, but give it a look and see if it answers any of your questions. https://www.reddit.com/r/SteamDeck/comments/yw1u2m/help_wanted_desperately_aoe_4_multiplayer/izu52o4?utm_medium=android_app&utm_source=share&context=3

Thank you! I'll give it a good read and see how we go when we follow those steps.

@Yohomie99 Those are commands to enter in a terminal (I believe the steam deck uses one called konsole). You'll need to navigate the terminal to the folder where the script is and run them. So, assuming the script is downloaded to the Downloads folder, you'll open a terminal and type:

1. cd Downloads or wherever the script is to navigate it's folder (cd means change directory)
2. chmod +x aoe4-mp-fix.sh This will allow you to execute the script
3. ./aoe4-mp-fix.sh This executes the script

However, I'm looking at this now with my steam deck, and this looks like it might be quite a bit more of a headache than I initially thought. Looks like it might be necessary to enable developer mode in order to download the dependencies and run the script.

You don't technically need dev mode to run this on the steamdeck. You can compile cabextract from source in a flatpak runtime. That's why I did just FYI.

Distrobox is great on the steam deck.

In the script edit:

$USER

in this line on the top:

STEAM_DIR=/home/$USER/.steam/steam/steamapps

You should have something like that:

STEAM_DIR=/home/goldnenex/.steam/steam/steamapps

install Distrobox and run the script from it.

Linux noob here (literally, day #3 of Kubuntu here). I ran the code with the set -ex to set -x tweak, and now AOE doesn't even open. Tried uninstalling and reinstalling, but no change, and now none of my games open. Anyone else run into this issue and solve it?

FYI this script does not account for the following scenarios:

1. If your games are stored on another drive, as in outside your home folder. I myself have two additional storage drives mounted elsewhere, since well, games are big and need to put them different places.
2. Once adapted to other locations, this script is also intolerant for spaces in parent folders where a Steam Library could be housed at. Like "/mnt/ssd-1tb/Steam Library" kind of deal.

I'm not sure what the best solution to #1 is, however for #2, double quotes are needed to surround the variables in the early parts declaring paths and sub-paths, and then also for the cd $dir step, should be cd "$dir", and the replace_dlls step needs double quotes around both 32 and 64 bit dirs.

The double quotes may be needed for arch too, but I could be wrong there.

I had to manually adapt the script for my situation and hopefully this helps someone else in the future.

Either way though, thanks for this script! \o/

For the people who have steam installed by snap, change:

STEAM_DIR=/home/$USER/.steam/steam/steamapps

to:

STEAM_DIR=/home/$USER/snap/steam/common/.local/share/Steam/steamapps

After this script with GE Proton still had the sync issue, it let me get an hour into the match before that tho. I was able to play through shorter matches no problem.

I've modified this to be a generic version of this to work with most other games by passing the APP ID. Also collected some additional examples for users so they don't have to edit the file directly (they still can though)
