ARMA III doesn't start

[xXRobbynatorXx]

Everytime I press Start I get an invalid image error.
"Exception Processing Message 0xc000007b Parameters 0x7ffc34cd1d28 0xc000012f 0x7ff34cd1d28 0x7ffc34cd1d28"

Exit code: 0xC00012F - STATUS_INVALID_IMAGE_NOT_MZ

I also have Windows 10

0xC000012F - STATUS_INVALID_IMAGE_NOT_MZ

These errors are raised when the EXE or DLLs, either in the game folder or in the system folders, are corrupted. Possible solutions:

• Verify the integrity of the game cache using Steam.
  
• Re-install DirectX.
  
• Uninstall the Visual C++ 2013 Redistributable package (x86 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 32-bit version of the Microsoft Dependency Walker and open arma3.exe with it. The corrupted library will be listed marked in the list.

I tried all of that and it still doesn't work

Try running w/out mods, running in admin, and/or running the game without using the launcher

Tried those as well.

Found that the file XAPOFX1_5.dll is causing the problems. But I already tried deleting it and downloading a new one. Deleting it and having the DirectX setup fix it and I also tried copying it from the SyWOW64 folder.

Hello xXRobbynatorXx,
actually the file in the SysWOW64 folder is the one that is corrupted (there is a file system redirection[msdn.microsoft.com] in effect, the System32 and SysWOW64 holds different versions of DLLs).

Try to run this fix, it will re-install the DirectX used by Arma 3: http://arma.jiripolasek.com/files/DirectX_Fix_For_Arma3.exe

Thanks Wizard works perfectly.

Ran into a problem. Because of the DirectX fix for Arma i couldn't play other games (like Astroneer) I had to reinstall the .dll file to be able to play those games. Of course Arma won't start anymore so I have to constantly switch between the files.

Hello,
that doesn't make sense. That fix only restores the correct 32-bit files for 32-bit programs.

What files (the exact path) are you chaning and what program are you using (Windows Explorer, Total Commander, etc.)?

[Wizard]

I've looked up the Astroneer game and according their site (and store) it's 64-bit game, so it can't share any files with Arma 3 (which is still 32-bit).

To be crystal clear:
- Arma 3 (as 32-bit app) uses files only from folder: C:\Windows\SYSWOW64\
- Astroneer (as 64-bit app) uses files only from C:\Windows\System32\
- the paths above might seem to be wrong (interchanged), they are not.

I downloaded the fix again and now both games are working.

It must of been something I did while trying to get Arma to work before asking on the Forum.

In other words my fault and everything is working now
