Hello,

This errors occurs when the EXE or DLLs, either in the game folder or in the system folders, are corrupted. Here are some possible solutions:

• Verify the integrity of the game cache using Steam.
• Re-install DirectX.
• Uninstall the Visual C++ 2013 Redistributable package (both x86 and x64 version), restart your computer and install the package again (do not use the Repair function).
• Run the Windows System File Check tool to repair corrupted system files.

To identify the precise DLL that is causing an issue.

• Download a 64-bit version of the Microsoft Dependency Walker and open arma3_x64.exe with it. The libraries with a red icon are the corrupted ones.
• Download a 32-bit version of the Microsoft Dependency Walker and open arma3.exe with it. The libraries with a red icon are the corrupted ones.

Try them out and if none of the above solutions help let us know and we will have a look at it further.
