Hello kinkykoala,

Sorry to hear about your trouble. Do you by any chance have a screenshot of the error message?

Regards,
JStewart

Hello JStewart,

I've uploaded a screenshot for you but ...

1. My windows is in dutch, the actual messages translates into english as :

c:\windows\system32\X3DAudio1-7.dll is unsuitable for windows or contains an error, try to reinstall the program from the original installation medium or contact your sysadmin or software vendor for support.

2. I must have seen this pop-up 100 times in the last 48 hrs and it's only after taking the screenshot that I noticed the "header" of the pop-up! It translates into english as : "DayZ.exe invalid installation copy" ...

if you require any more info, don't hesitate to ask.

You did Download Dayz From Steam correct?, if so Uninstall Dayz Completely, then go to your Steam Library and Re-download it from there

Hmm, it seems like MS have run into this problem before. To begin with, could you try having a look at the following post please (maybe a re-install of the DX redistributables might help)?

Deleted & re-installed DayZ 3 times but I still get the same error message ...

Found a post somewhere that said to uninstall the game, delete all X3DAudio1 files and replace them one by one. Only after this is done can you re-install the game ... Will try that now.

That link you posted above seems to be more for win8, I'm running win7 home premium 64bit but I'll definitely give it a look.

will post results good/bad

Nope, that didn't work either ...

I have deleted dayz , updated all X3DAudio1_* files by hand and re-installed DayZ but kept getting that same error message.

Tried some stuff in that link you posted too :

• downloaded runtime package & installed it ... same result.
• ran dxdiag but couldn't see anything that "jumped out"

I find myself at my wit's end ... JStewart, I'm in need of your magical powers
;)

PS what also drives me nuts is that this only happens with DayZ, I can play left 4 dead or arma2, even DayZmod I bet ( didn't actually try to play the mod ) but DayZ Standalone seems to be "off limits" to me at the moment ...

EUREKA !!!

It works :)))

I'm still not exactly sure how I fixed this but I managed to get it running
by following the instructions under "method2" in the following link :

http://gamunation.com/x3daudio1_7-dll-missing-error-fix-windows-78skyrim/

What little I understood is this : even though I'm on a 64bit OS for some bizarre reason I needed to download the 32bit .dll version instead of the 64bit version. (my error message didn't say the file was missing / couldn't be found, it just said that it was "unsuitable" for windows )
I installed the 32bit.dll into dayz folder, windows/system32 AND windows/wow64 folder.
Rebooted my PC and started dayz for the first time in approx 72 hours.
(just in time , I was starting to experience severe withdrawal symptoms )

JStewart , my first kill in 0.58 will be dedicated to you !

I'm off, thx for your time dude !

Done, killed a guy in elektro police station, he had a magnum,
I had a cr75, the last words he heard were :

"You have been sacrificed to the dayz gods, I dedicate this kill to JStewart"

Mahalo

Wasting no time I see, haha. I'm very happy to hear that all is working now :)

If you run into any other problems, just file a new ticket and we'll have a look.

Regards,
JStewart
