Hello rengoku,

To begin with I would recommend that you try out the following steps:

1. Move the entire "C:\Program Files (x86)\Steam\SteamApps" folder to your desktop. Your "SteamApps" folder should now be at the following location: "C:\Users\<username>\Desktop\SteamApps".
2. Move the "DayZ" folder out of the "C:\Users\<username>\Desktop\SteamApps\common" folder and subsequently delete the "DayZ" folder.
3. Uninstall Steam while making sure the "SteamApps" folder is still on your desktop.
4. Install a new version of Steam.
5. Go to the new "C:\Program Files (x86)\Steam\SteamApps" folder.
6. Move everything inside the old "SteamApps" folder on your desktop to the new "C:\Program Files (x86)\Steam\SteamApps" folder.
7. Install DayZ again.

In case this does not solve your problem either, I can have a look at your account in the character database if you send me a link for your Steam Profile ID.

JStewart

Am I able to just get a refund on this? I now cannot play half of my steam games because of a 'missing executable'. I have tried to make this game work for hours, and now I have just made it worse. If the game can get further developed then I will be more than willing to spend more money on it - however I dont think its fair that I have to pay for a game that I want to play (and enjoyed it as an Arma2 mod) and doesnt work because of how it was installed onto my computer.

It was a suggestion based on what has solved the problem for others. We cannot confirm if the problem is related to the install process itself. In case the problem persists, please send in a link for your Steam profile and I'll see if the problem is related to your account in the character database.

As for a refund; did you purchase the game via Steam?

This is how you fix it. I tried everything you listed, but once i did this it finally worked. Go to steamapps in the steam folder and move it to your desktop(might take awhile depending on how many games you have installed). Then once it's on your desktop, move dayz out of the common folder in steamapps and delete it. Make sure the steamapps is still on your desktop and uninstall steam. Once you have steam uninstalled, install a new version of steam from the steam website. Once the new version of steam is installed, go to the new steamapps folder in the steam directory and move everything from the old steamapps folder on your desktop to the new steamapps folder. Once you did that, install dayz again and it should work. This guy also tried it and it worked, here is his post http://feedback.dayzgame.com/view.php?id=19656&nbn=3#bugnotes
