Hi there, im not a supporter but i had or I have the same issue and I found out how to fix it "TEMPORARILY".

I think u bought the game from steam.
First u go to the DAYZ game folder where the dayz.exe and DayZ_be.exe is.
It could be like this "E:\Games\Steam\steamapps\common\DayZ"
Then u start the game from the DayZ.exe u could get now 3 errors.

1. Steam says game can´t be started
2. couldn´t start Dayz.exe
3. Some memoryshit error

but if u click them away DayZ will start anyway.

Now if u close Dayz u can normaly start it from steam without any error.

But if u restart your PC u will get the Side by side error again and must start it throgh the DayZ.exe again.

best thing to do is to make a shortcut on ur desktop and wait for an official fix.

Hope it will help u and ur friend to play DayZ again.

Hi thank you for trying to help but unfortunately your method did not help any of us with the problem i tried to do a system restore and it worked for a few hours but when i restarted my pc it went back to the same problem.

Hello caparossa,

Sorry to hear about your trouble. To begin with, please attach a dxdiag report to this ticket:

1. Open the Start menu
2. Write "dxdiag"
3. Press enter
4. A window will open
5. Click "Save all information"
6. You will get a text file - that's what we need

Also, could you attach a screenshot of the error message please?

Thanks,
JStewart

Hello JStewart please let me know if you need any more information i am eager to get back on dayz

Thanks for sending in that info. The drivers for your graphics card is from last july. Could you try updating all your hardware drivers and also add the contents from your "C:\Users\<Name>\AppData\Local" folder to this ticket please?

You can add the folder in a .zip/.rar archive and then upload it to this ticket. The upload limit is 5000KB, which should be enough. In case it is not, please upload the files to a file sharing website and post a link to the files in the comments.

Thanks,
JStewart
