  FIX: Titanfall 2 Error 0xc000007b (STATUS_INVALID_IMAGE_FORMAT)
======================================================================

WHAT THIS ERROR MEANS
---------------------
0xc000007b = "STATUS_INVALID_IMAGE_FORMAT". A 32-bit program
(ActivationUI.exe) is trying to load a 64-bit DLL and Windows
rejects it.

The culprit: C:\Windows\SysWOW64\msvcr120.dll has been corrupted
with the 64-bit version instead of the 32-bit one (likely from a
bad VC++ runtime install/uninstall).

WHAT THIS FILE CONTAINS
-----------------------
This text file has the FIX script embedded below the "---CUT HERE---"
line. You extract it and run it to fix the problem automatically.

INSTRUCTIONS
------------
1. Open this file in Notepad.
2. Select EVERYTHING from "---CUT HERE---" to the end of the file.
3. Copy it (Ctrl+C).
4. Open a new file in Notepad, paste it (Ctrl+V).
5. Save it as "fix_0xc000007b.ps1" in this same folder
   (Core folder next to ActivationUI.exe).
6. Right-click the saved fix_0xc000007b.ps1 and select
   "Run with PowerShell", OR open PowerShell as Administrator
   and type:
       cd "G:\SteamLibrary\steamapps\common\Titanfall2\Core"
       .\fix_0xc000007b.ps1

The script will:
  - Find or download the VC++ 2013 x86 redistributable
  - Extract the correct 32-bit msvcr120.dll from it
  - Replace the corrupted copy in C:\Windows\SysWOW64
  - Place a local copy in the game's Core folder
  - Test ActivationUI.exe to confirm the fix

After it finishes, launch Titanfall 2 through Steam normally.

IF IT STILL FAILS
-----------------
- Make sure you ran the script as Administrator (required to write
  to C:\Windows\SysWOW64).
- Install ALL Visual C++ Redistributables (x86): 2005 through 2022.
- Run these as Administrator:
    sfc /scannow
    dism /online /cleanup-image /restorehealth
- Add the game folder to your antivirus exclusions.
- Run __Installer\directx\redist\DXSETUP.exe from the game folder.

WHAT NOT TO DO
--------------
- Don't download random DLLs from the internet (malware risk).
- Don't reinstall Windows (it's one file, not your whole OS).
- Don't disable your antivirus permanently (just add exclusions).
