I'm getting the very same error in my launcher. Has been happening since the 1.19 update.

I just helped out a friend that just had this issue today, and at least in his case, a simple workaround seems to have done the trick. He had already had done a full uninstall/reinstall the game and local files, and had wiped his workshop folder, but was still getting this error.

  1. In steam, go to settings-downloads and click 'steam library folders' on the right hand side of the window will be a box with 3 dots, click and select 'repair folder'
  2. in the DayZ program folder, right click dayzlauncher.exe and select Run as Administrator.

If that works, you can set it to run in admin mode every time if you right click dayzlauncher.exe and go to the compatibility tab. The only noticeable side effect is that every time you start the game, you will have a popup box to allow the launcher to run as an admin. No big deal, really.

Worth trying at least.

Sadly it did not work. Wish BI would just help me solve the issue, seems they give zero shits about people's problems.
