Playing with friends / multiplayer

Play Escape From Tarkov (Live) here.

SPT-AKI won't have multiplayer capabilities. If you ever find videos of people playing with others, it's not made by the SPT-AKI developers and is not related to it.

How to downgrade your EFT version

How to use the downgrader in steps:

Follow these steps once you have the downgrader downloaded as well as the current latest files of SPT of this time.

0.) Run an integrity check on your Live EFT game. Some files, such as level177, may be missing in the Live game and they would not affect your live gameplay. This is NOT the case for downgrading your client. Missing such files could potentially prevent a successful downgrade.

1.) Have the contents from Live EFT Folder copied and pasted into a new folder (where you are going to keep SP EFT).

2.) Extract the downgrader's files (with 7zip, winRAR would cause unnecessary complications) into the folder (where you are going to have SP EFT) and run downgrader.exe.

2.5.) Make sure downgrader.exe keeps running until it is complete. It should let you know.

3.) Once that process is complete, extract all of SPT files that had been downloaded into the folder (where SP EFT is located).

4.) Run Server.exe and Launcher.exe. Enjoy.

Downgrader link: SPT-AKI Patcher

Make sure to verify that the clients you own is compatible first

Requirement: Windows .NET 5.0 (please download and install on your own)

I can't unzip something!

When you are trying to unzip a file, and get something along the lines of this as an error code

! E:\Escape From Tarkov - Copy\Patcher_12.11.2.13615_to_12.10.2.12893.7z: Cannot open C:\Patcher_12.11.2.13615_to_12.10.2.12893\Aki_Data\Patcher\EscapeFromTarkov_Data\StreamingAssets\Windows\assets\content\items\equipment\armor_custom_thorcrv\item_equipment_armor_custom_thorcrv.bundle.manifest.del
The system cannot find the path specified.

Try opening the file in 7zip, as it has a .7z extension it must be extracted/unzipped/etc via 7Zip which you may find here.

Can you sell items on the flea market.

Yes, but not for barter.

How to install AKI
Does the latest AKI version contain airdrops?

Yes! As of 3.2.2, airdrops are functional again.

How do I backup my profile.

Navigate to your EFT-AKI directory, then user/profiles.
Copy containing files and save them elsewhere on your computer.
If you encounter issues where you need to revert, you can then delete the contents of user/profiles, and transfer your backup files back in.

Launcher issues

I am asked to Install .NET 5

You need to install this to be able to start the launcher.

No servers are available

Make sure that Server.exe says that the server is running, then press the refresh button in the launcher.

No connection can be established

Make sure that Server.exe says that the server is running.

Error: "Object reference not set to an instance of an object"

Make sure you played EFT (Live) at least once on your current windows installation.

  1. Start the server (Server.exe).
  2. Start the client (EscapeFromTarkov.exe).
  3. Wait about 10 seconds on the game loading screen.
  4. Close the game (Alt + F4).
  5. Start Launcher.exe.
Cleaning the temp files
  1. Open the launcher.
  2. Click on the cogwheel in the right upper corner.
  3. Click the clean temp files button.
Launcher is hanging at on the patching progress bar

That means your EFT installation path is incorrect.

1. Open AKI/user/launcher/config.json

2. Change GamePath to your current AKI installation. (Change "\" to "/")

Escape From Tarkov isn't installed on your computer.
  • Make sure you have already started at least one time the official game and completed one raid.
  • Make sure SPT-Aki launcher game path is correct
  • If it still doesn't work, apply again your game repository in BSG launcher
  • Start the game
  • Complete a raid


Server issues

How to install mods

Mods archives (.zip) content need to be extracted into [Your AKI directory]/user/mods/ and need to looks like the following images

Unless specified by the mod authors, all mods are installed the same way.


Port 443 is already in use. check if the server isn't already running

If you are encountering this issue, that means you are running an application that uses the port 443. The applications that usually use that port are:

  • Virtual Machine applications(VMWare...).
  • Web servers applications (wamp, xamp, apache...).

Or, you can use mods that let you change the port. eg:

SPT-Aki Configurator

I am getting a Cannot read property 'Price' of undefined error when going in a trader

Error type:

Then the solution is simple

This is most likely caused by a mod that isn't correctly updated to AKI.

Follow the below instructions


Check your mod list and their respective mod page to know if they are updated for the version you are using.

- Remove the mods one by one to find which mod is causing it.

- Once you found the mod, remove it from your mod list.

- Make sure that you don't have any item from the mod you are removing in your inventory, if you do, delete them first of your inventory.

- Restart the server and the game.

Game issues

⚠️ Close both the game and server when editing the profile⚠️ .

  1. Open <server>/user/profiles/yourProfileID.json in VSCodium.
  2. Search for the number appearing in the error
  3. Remove the ".5" of the number
  4. Save the file

Endless loading / Stuck on splashscreen / Game crash to desktop

Possible error message:

Failed to load assembly ...\Aki_Data\Modules\aki-core\./module.dll

Failed signature check from '...\Aki_Data\Modules\aki-core\./module.dll'


2022-01-24 16:31:50.678 +01:00||Error|Default|

EXCEPTION: System.InvalidCastException: Specified cast is not valid.

Five causes:

1. Your client version is wrong

2. You changed your FOV to higher than official game can

3. You're missing one of the prerequisite .NET runtimes - either .NET Framework 4.7.2 or .NET 6

4. Your antivirus is blocking the module.dll patch

5. Your game files has some residual old files that cant be used (specifically for EasyAssetPatch error)


- Make sure you are using the correct client version according to your AKI version (clients needed can be found on the download page)

- If not, check if a patch exists for your game version to downgrade to the needed version(Versions supported are found on the patcher page)


- Go to MyDocuments/EscapeFromTarkov/ and delete shared.ini file


- Download .NET Framework 4.7.2 and .NET 6 Runtime. Order does not matter.


- You need to whitelist the module.dll file. This can be found in ...\Aki_Data\Modules\aki-core\module.dll

- Redownload and copy the Aki files into your install directory

- Delete everything relating to EFT and SPT

- Redownload EFT and start the install process for SPT again.

Game crashes to desktop (2.3.0 and newer)

If your game crashes to desktop before you even see the initial loading screen, and no LogOutput.log file is generated in the /BepInEx directory, you might see a preloader_*.log file generated near your game .exe

If probably contains an error that starts like this:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> HarmonyLib.HarmonyException: Patching exception in method static void Console::SetOut(System.IO.TextWriter newOut) ---> System.MissingMethodException: Mono.Cecil.MethodDefinition MonoMod.Utils.DynamicMethodDefinition.get_Definition()
  at HarmonyLib.PatchClassProcessor.ProcessPatchJob (HarmonyLib.PatchJobs`1+Job[T] job)

It's very likely you installed AKI 2.3.0 (or newer) on top of an old AKI version. Please completely delete your old SPT folder and make a fresh copy from Live before installing AKI 2.3.0 or newer.

Using the underbarrel grenade launcher

The underbarrel grenade launcher (GP-34) have issues when reloading that will block your character and prevent you from anything else in a raid.
It's not meant to be useable (at the moment), otherwise it would be available on the official game.

There aren't a lot of PMC in my games.

Option 1.

  • Download SPT-Aki Configurator mod
  • Install the mod (duh), under config.json, adjust the line under assault (line 45) to the percentage of your liking.
  • What it does is changing the assault (scav) class that spawn to become AI PMC. Unit is in percentage, say if you want 3 pmc per every 10 scav spawn, change that value to 30.

Option 2.

Do this option at your own risk.

  • Heads to AKI-Data>Server>eft-bots>src>config.js.
  • Look for line "assaultGroup" line 43.
  • Add an addtional line with "assault":(your desire spawn chance)

Don't forget to add a comma "," on above line when adding a new line.

Additionnal note:

"isUSEC" is the how much PMC would spawn at USEC, Bear would be the remaining number after deducted by 100. If you are USEC and would only like to battle BEAR with no AI teammates, adjust that number to 0. That will be interpreted as usecChance in the AKI-config mod.


I can't extract from my raids!

pressing "O" and getting no extract list? Or screen goes black and doesn't load?
sorry this is a BSG bug and you'll need to either die and it be a loss or alt-f4 and it's like the raid never happened

Marked room, valuable places, or general world loot is low/missing

This issue is caused by one thing:

How we manage the spawning of loose loot. AKI does spawn loose loot differently than official servers, and we still use official multipliers values which make it really, really low.

So no, having your marked rooms empty aren't an issue ! Loot spawning is completely different, and doesn't always give you what you expect.

I'm missing a few weapons from my preset list in game

One or more guns are missing from your preset list ? Don't worry ! I'll explain you why, and how to fix it, if it can be fixed.

Can't load into any map, xx.bundle not found

When loading on any map i am getting this error:

This error is simple ! Follow the below instructions


This error usually happen for a simple reason: You have special characters in your path to the game.
For fixing it, you simply need to remove any special character from your path (from your drive letter, to your game .exe).

- This error can aswell happen if you run your game from Microsoft OneDrive cloudsync. If you do, remove the game from the OneDrive cloud and put it somewhere else.


Can't gather my bitcoins

If you can't gather your bitcoins, don't panic!

You need to wait for one more bitcoins to be able to collect the bitcoins. Since BSG is messing a lot with bitcoins, and that they are hardcoded, it is hard to keep up with these changes. So what you see in game isn't what you really have.

So patiently wait for a second bitcoin to be done before collecting one bitcoin

Can't buy something: You don't have some items required to finish the deal.

This is not an issue! Make sure you have checked the box at the bottom of the trade screen, or, make sure to click on "fill" button before willing to trade.
Also make sure that you have all the items in your stash, and not on your character stuff.


Item icons are incorrect
My scav karma resets when I finish a scav raid! / My scav karma does not take effect in-game!

If you tried to change your scav karma value by editing your profile, make sure you edit it for both your PMC AND your scav.

Cant find my screenshots at the location the game said

Current AKI versions with this issue:




There is no easy way to fix this, so for the time being print screen and paste to paint.

This will be fixed in a later release!

PMC dies on raid start! or Missing textures!

Sometimes this can be logged into your client logs:

2022-04-25 15:53:57.662 -05:00||Error|Default|CollisionMeshData couldn't be created because the mesh has been marked as non-accessible. Mesh asset path "" Mesh name "fabric"
2022-04-25 15:53:57.662 -05:00||Error|Default|CollisionMeshData couldn't be created because the mesh has been marked as non-accessible. Mesh asset path "" Mesh name "metal"
2022-04-25 15:53:57.662 -05:00||Error|Default|CollisionMeshData couldn't be created because the mesh has been marked as non-accessible. Mesh asset path "" Mesh name "plastic"

but if you are missing textures, falling through maps, dying before the raid starts, this is relevant:

1. Delete all game files to do with EFT and SPT.

2. redownload EFT from BSG's launcher,

4. restart the SPT install process
