@XENONFFM, does the game crash when playing single player or other multiplayer missions?

Try the below possible solutions one-by-one:

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

If the crash persists after trying all of the above possible solutions then use the Arma 3 Launcher to prepare a troubleshooting report and then upload the report to the feedback tracker for the developers to review.

For issues regarding Arma 3 you can file a troubleshooting report, also via an action available in the option menu in the upper right corner (gear icon)

Be sure to upload the whole report file. If the report file will not upload directly to the feedback tracker then try uploading to a free file sharing service such as Dropbox, Microsoft OneDrive, Google Drive,, and so forth, and then link to the report file in a comment below.

Hi, please send us your troubleshooting report contains files .rpt, .mdmp and .bidmp.

Thank you

Thanks for your fast replies!

@Jawsh: I will try your solutions out but I wont get any error code when Arma 3 closes so I cant try out the second solution.

@Alwin: I uploaded the last two .rpt files out of my user>local>Arma3 folder but i cant find .mdmp or .bidmp files in this and the Arma 3 directory (where are they located?).
Google Drive files

Thanks - Xenon

You´ll get it via Launcher troubleshooting report.

Crash reports are all saved here: C:\Users\*username*\AppData\Local\Arma 3

We need all three file types to check your problem and resolve it.

Thank you.

Hey @Alwin,

I made an crash report and uploaded it to the same Google Drive folder (Google Drive files).
Like i said there are no .mdmp & .bidmp files in the C:\Users\*username*\AppData\Local\Arma 3 directory, I looked in each folder but i cant find any :( there are only .rpt files. I put a screenshot of the C:\Users\*username*\AppData\Local\Arma 3 into the same folder.

Thanks - Xenon


I searched my whole drives for any .mdmp & .bidmp files and I only found one in the C:\Users\user\AppData\Local\Arma 3 Launcher
directory but it is not up to date. The file is from 02.11.16 where i had not these issues.

Okey, thanks for effort

It seem that problem is on the KOTH side. You can try some of these solutions and if they won´t help you. I´ll ask you to wait until next update or try to switch to profiling build.

Step 1.
Try to decrease your game graphic quality.

Step 2.
Try another KOTH server.

Step 3.
Try to reinstall Arma 3.

Step 4.
You can try the last possible solution called All in One Runtimes tool.

  1. Download All in One Runtimes
  2. Tool will repair your Visual C++, Java SE, Adobe Flash Player, Adobe Shockwave Player, Silverlight, DirectX
  3. Restart computer
  4. Uninstall the tool
  5. Launch the game

Hope it will help you.

Let me know.


I will try it this weekend

I still have the same issue.
Here are the requested files:

Arma 3 uses only ca. 4Gb of 10Gb free ram.
Arma 3 on a SSD and the 64 Bit version doesnt help

Thanks Xenon
