@TheSaltySilver and @makkyzr, what version and branch of the game are you two using? Use the Arma 3 Launcher to copy the info to the clipboard. Could you two also prepare and attach a troubleshooting report below?

Launcher version: 1.5.139565

Game version: 1.66.139586

Branch: main / beta branch not specified

this is the troubleshooting report i saved from the launcher. Hope this is what you are asking for and thank you :)

@makkyzr, that's it.

== "E:\Steam\steamapps\common\Arma 3\arma3.exe" -noSplash -nosplash -cpuCount=6 -high -mod= -connect= -port=2302

-noSplash is listed twice. One of them can be removed.

-high is not a valid launch parameter and can be removed.

Try restarting your computer and then verifying the integrity of the game cache for Arma 3 even if you have already done this prior. Next add -checkSignatures to the launch parameters then try playing the game again. Once you are done prepare and attach a new troubleshooting report below.

@Jawsh here we go

Latest arma3.rpt looks okay. I am not sure what else to suggest.

@Jawsh oh ok thanks for your time my friend I really appreciate it :) any idea to whom should i report this? Is there a way I could make this noticed by the developers? Because all I find when i search about this problem is more people having the same situation with no resolve or solution found at all

You're welcome. As you have already submitted a report (T122832) it is just a matter of waiting for the developers to acknowledge and respond to it. They do have quite a number of other tickets to address.

Try to delete your profile folder (create a backup) a try to start the game.

The file yourprofilename.vars.Arma3Profile must be deleted.
Path: C:\Users\*username*\Documents\Arma 3

@Alwin I did. The problem still persists

Alwin changed the task status from Reviewed to Acknowledged.Jan 26 2017, 1:48 PM

Did you check if you´re connected to Steam? Next, check your game client version or change your user name.
Also, connecting to almost full server equals automatic kick, e. g. server has 110/120. The last ten spots are most likely reserved.

makkyzr added a comment.EditedJan 26 2017, 8:16 PM

@Alwin yes i am connected to steam.
Launcher version: 1.5.139565

Game version: 1.66.139586

Branch: main / beta branch not specified

and no i don't join almost full servers, i try to join the official servers having 5 or less players.

I'm sorry but how do I change my username?

Alwin added a comment.EditedJan 27 2017, 9:07 AM

Main Menu>Avatar icon in right upper corner>Click on your name>Profile>New

@Alwin Done, still the problem persists I'm afraid. I have noticed that it says user uses modified data upon joining. Could that be the problem?

Alwin added a comment.Jan 30 2017, 9:14 AM

@makkyzr Yes, most likely modified data can cause this problem. I recommend you to unload all of them and re-download. You can make an update or repair. Sometimes, they are not downloaded directly to addons folder and it´s better to check where are they a copy them back.

@Alwin I'm sorry but how do I unload them? I don't remember modifying something so I'm not quite sure as how to "undo" it

Open Launcher>Parameters>Basic/Advanced parameters
Launch game in windowed mode and check upper strip where are all loaded paramteres shown.

makkyzr added a comment.EditedFeb 1 2017, 1:01 AM

@Alwin I have unchecked the parameters. Only had skip logos. In windowed mode I've noticed that it says "-mod=" at the end after my games path. Is that normal?
Also it still said using modified data upon joining game and I was shortly kicked out. I have also tried launch game without mods option.

Alwin added a comment.EditedFeb 1 2017, 12:17 PM

Hi, -mod= is sign for loaded parameter. This is related to skip logo parameter in this case. It´s normal. As I said before some servers has reserved spots and some players are kicked any time. BattlEye sometimes decide that player is not allowed to enter to server and kick him out for some reason.

@Alwin But i removed all parameters, even skip logos and it still said -mod= and "using modified data" message upon joining a game and got kicked (signature check timesout is what others see)
I only join official servers with only 2 or 3 players playing so the server is almost empty and being kicked for a reserved spot is not a possibility.
About battlEye, I tried joining a server that does not require battlEye and I got the same problem and got kicked.

Alwin added a comment.Feb 2 2017, 8:56 AM

@makkyzr I´d help you to change your profile name.

@Alwin I don't understand? I have already changed my arma profile name as you have suggested earlier

Alwin added a comment.EditedFeb 3 2017, 9:24 AM

Oh, sry...I didn't realize what I earlier recommending. There are many tickets.

I´ve found in your rpt THIS:

16:04:06 Error in expression <n {BIS_RscRespawnControls_escHandler =
BIS_RscRespawnControlsMap_display displa>
16:04:06 Error position: <BIS_RscRespawnControlsMap_display displa>

16:10:43 Error: weapon [bipod_02_F_blk] still has its shape, ref_count=8

Try reinstall your Visual C++ Redistributable.

makkyzr added a comment.EditedFeb 11 2017, 9:32 PM

@Alwin ok i am really confused as how to do this? I know how to uninstall it, but what do I need to download and from where? and which years?
Also sorry for the late reply! Lots of work
edit: i think i figured it out, going to try the game when i am done

Alwin added a comment.Feb 13 2017, 1:50 PM


You should try this.

Try restarting your computer and then verifying the integrity of the game cache for Arma 3.

  1. Restart your computer and launch Steam
  2. From the Library section, right-click on the game and select Properties from the menu.
  3. Select the Local files tab and click the Verify integrity of game cache... button.
  4. Steam will verify the game's files - this process may take several minutes.

Try all of the possible solutions listed on the Arma 3 Unusual process exit article on the Bohemia Interactive Community Wiki.

Try switching to and playing on the profiling game branch. After downloading new data verify the integrity of the game cache.

• profiling branch (special performance + profiling build - requires access code: CautionSpecialProfilingAndTestingBranchArma3), alternative download of needed binary possible from Dwarden's dropbox

Try to delete your profile folder (create a backup) a try to start the game.

The file yourprofilename.vars.Arma3Profile must be deleted.
Path: C:\Users\*username*\Documents\Arma 3

So, there is some next solutions.

try to decrease your graphic quality (if you're using ultra set high or medium). It´s possible that your have no more space on your GPU.
reinstall your GPU drivers

I have already tried restarting and verifying game cache
My problem is not an unusual exit, I never get an error like that my problem is just getting kicked 99% of the time 2 minutes after joining a server (signature check timeout)
Already tried deleting my profile
My GPU is 960 gtx with 4 gb vram I think its not too bad to play the game, but i actually did already lower all graphics but it didn't help.

I will check on the profiling branch thingy and I'll post here the results when I do :)
I'm probably gonna reinstall the game

makkyzr added a comment.EditedFeb 16 2017, 10:03 AM

@Alwin Re installed the game, still the same problem and still got the "uses modified data" message
Not sure if I did the profiling branch thing right. I put the code into the betas menu in properties and launched the launcher, joined a zeus official server. Didn't work, still got kicked

@Alwin any other clues?? do the developers even know about this? and if there is no fix could i at least be eligible for a refund???

@Alwin if not then i thank you a lot for your efforts but please unassign so that other members and hopefully a developer may notice the thread and know that it is unresolved :)
