To solve your problem we need dxdiag and files from this folder: "C:\Users\<Name>\AppData\Local\DayZ\"

Can you pack the files in winrar and upload it somewhere please?
When the *.rar will be smaller than 2.097k, you can attach it here. Thank you.

When reporting please refer to "How to guide" http://feedback.dayzgame.com/how-to-user.html

have the same problem. tried to delete my .cfg (both) and dayz created new ones, didnt work.
validated as well.
worked yesterday.

EDIT: FIXED it by turning on windowed in cfg
alt-enter does work for a short time but crashes.

My apologies, it was late & was desperate to try SA :)

Requested info is here:

Let me know if you need anything else.

<edit>And now dropbox is down...just not my day! File mirrored here:

I got this problem at the first start of DayZ. I just "validate the steam gamefiles" in steam and that solved that problem.

Right-click in steam on dayz - properities - validate game files...maybe it works for you

Just did it again for fun - no joy

Windowed did not work for me...

runs now for me... didnt change anythingm even fullscreen

I am running QHD screens and because they are not able to downsample they just turn black. Then i have to press ALT+ENTER to get the windows to appear! Also got the Crossfire bug with only one card running!

Tonights update:
Got a few more seconds at Bohemia logo, then error.jpg (see RAR)

Steam applied new update
Delete dayz/other profiles folders in My Docs
Launch DayZ = error.jpg (see rar)
Verify DayZ via Steam integrity check = 1 file corrupted - re-downloaded
Check DayZ.cfg = still truncated
Again, delete dayz/other profiles folders in My Docs
Re-launch DayZ = Back to original issue.
DayZ log update = https://www.dropbox.com/s/rknoyg9iisusr45/DX_part_2.rar

I should mention I am running multi-monitors, but not for the game, besides I have tried with a single monitor - no difference.

Also: Take On Helicopters, ARMA2,ARMA2:OA,BF,PMC are working OK.

I know they are not the same engine, but until I get a better suggestion I believe this indicates a dayz problem & not my PC.

This issue was processed by our team and is being looked into. We thank you for your feedback.

Please keep the issue monitored to see when it is fixed.

Tonights update:

Steam download/applied update 0.29.113822
Launch DayZ = Crash to desktop
Delete dayz/other profiles folders in My Docs
Success, after ~10sec on Bohemia Logo & 20 on DayZ logo I'm in!
Configure Video settings & Save
Quit & relaunch = crash to desktop
Check DayZ.cfg = full version
Verify DayZ via Steam integrity check = OK
Delete dayz/other profiles folders in My Docs
Launch DayZ = Crash to desktop

Have included the new dayz.cfg in the RAR:
https://www.dropbox.com/s/mecjj4z93qif54u/DayZ%20Part%203.rar

There is problem with generating of shaders, that can be caused by multiple things:

1. If you have active some mods.
2. If your data are corrupted.
3. If your drivers are outdated (or if you are using beta drivers)
4. If you are using any 3rd party technology like Oculus rift or similar things.
5. If you dont run Steam as Administrator.

Are you using multiscreen, or eyefinity?

Try this:
Open Steam -> Library -> right click on DayZ -> Properties -> General -> Set launch options -> and write here: -disableShaderGeneration
Then try to run the game.

1. No mods
2. DayZ data? Sometimes OK, sometimes not. See step 15 in next post.
3. Have tried Catalyst 13.9, 13.11 beta9.2, 13.11 beta9.5 & will be trying 13.12 after work
4. Only MS Sidewinder 2 Joystick & 3rd party Microphone
5. Who runs Steam as Administrator? :) I will try this though.

I use dual monitors, 2 x 1920x1200, controlled by DisplayFusion. I am trying to run DayZ on primary monitor only. I have also unplugged 2nd monitor with no change. No eyefinity.

This happens on all Catalyst revisions I have tried, currently 13.12 release:

1. Launch DayZ (-disableShaderGeneration) = crash to desktop
2. Delete dayz/other profiles folders in My Docs
3. Launch DayZ (-disableShaderGeneration) = DayZ Menu
4. Quit DayZ (NO change to any cfg, settings etc)
5. Launch DayZ (-disableShaderGeneration) = Crash to desktop
6. Launch DayZ (-disableShaderGeneration removed) = Crash to desktop
7. Delete dayz/other profiles folders in My Docs
8. Launch DayZ (-disableShaderGeneration removed) = DayZ Menu
9. Quit DayZ (NO change to any cfg, settings etc)
10. Launch DayZ (-disableShaderGeneration removed) = Crash to desktop
11. Launch DayZ (-disableShaderGeneration) = Crash to desktop
12. Delete dayz/other profiles folders in My Docs
13. Launch DayZ (-disableShaderGeneration) = Crash to desktop
14. Launch DayZ (-disableShaderGeneration removed) = Crash to desktop
15. Verify via Steam = '1 file failed to validate', re-acquiring.
16. Delete dayz/other profiles folders in My Docs
17. At this stage DayZ will ALWAYS go to menu with or without shaders enabled, but when DayZ quits the next launch always crashes.

Repeating steps 15 & 16 usually launches to DayZ menu. But when DayZ quits, things go wrong.

Will post Steam\logs\content_log.txt (integrity check log) when I get home.

Also my Steam username is 25 characters & is truncated in menu screen. Will that cause any problems?

Steam in Admin mode did not work any differently.

Edited post for clarity, was a bit of a mess earlier...

Did Steam show you which file failed to validate?

Are you using some overclocking software?

Also try to disable your antivirus software and then run the game.

Thank you for your feedback a patience.

No overclocking on CPU/GPU/RAM.

A/V is MS Security Essentials - disabled - added exception for Steam folder - no change.

Unity, Frostbite, Source & Unreal engined games are all running OK on my system from the same SSD.

SSD diagnostics = SSD is 100% ok

Here's the Steam log, sorry it's late, I work nights:

https://www.dropbox.com/s/br3lgs6fplxulfg/content_log.txt

This stands out:
[2013-12-20 20:35:26] Validation: SHA mismatch "R:\Steam\steamapps\common\DayZ\dta\bin.pbo"

Update: 0.30.113860 always crashes, usually before Bohemia logo -disableShaderGeneration on or off.

Steps from post above (0003746) do not launch to DayZ menu anymore. :( UPDATE - now working as well as previous patch - forgot to reboot!

Always this file corrupt: "R:\Steam\steamapps\common\DayZ\dta\bin.pbo"
Steam replacement file is either ~32Mb or ~430kb with no pattern I can see.

Do you need any more files?

I am having the same problems just updated catalyst to the latest version which came out a couple weeks ago thinking it might help. Didn't work. i think it may have something to do with the AMD Gaming program which tracks game progess and allows you to control settings from outside the game not sure if anyone else has this program. Going to uninstall and test tomorrow.

dev's dont care about this problem...same problem nobody helps me.

Just tested without AMD tracker didnt work. #sad cant play

Please let us know if you are still able to reproduce this issue in latest Development build.

If so send us from this folder:
"R:\Steam\steamapps\common\DayZ\dta\"

these files:
bin.pbo.dayz.bisign
bin.pbo

and from this folder:
"R:\Steam\steamapps\

this file:
appmanifest_221100.acf

After you send them, delete whole "dta" folder in "R:\Steam\steamapps\common\DayZ\" and download dta.rar from https://www.dropbox.com/s/a4shg2envs0tjjp/dta.rar and replace your deleted "dta" folder with it.

Hey there,

we have done some adjustments based on the crashdumps you have provided. Please update your game to the latest experimental build and try to reproduce the issue one more time.

Thank you!
