Hi,  
I try to load libjulia.dll dynamically win32 version libjulia.dll on Windows but loadlibrary fails.  
using LoadLibrary from C++  
It fails on win32 with error:  
Unable to load dependent library D:\julia-1.11.3-win32\julia-1.11.3\bin\libjulia-codegen.dll  
Same code with x64 build works perfectly (julia and my code).

I can also reproduce using python loading library on win32 (python and julia) it fails:

```python
import os
import ctypes
julia_directory = 'D:/julia-1.11.3-win32/julia-1.11.3/bin'
os.chdir(julia_directory)
print("Current Directory:", os.getcwd())
julia_dll = 'libjulia.dll'
library_path = os.path.abspath(julia_dll)
julia_library = ctypes.CDLL(library_path)

```

result:

```julia
D:\Developpements\Github\nelson-lang\nelson>python
Python 3.13.1 (tags/v3.13.1:0671451, Dec 3 2024, 19:06:28) [MSC v.1942 64 bit (AMD64)] on win32

>>> os.chdir(julia_directory)
>>> print("Current Directory:", os.getcwd())
Current Directory: D:\julia-1.11.3-win32\julia-1.11.3\bin
>>> julia_dll = 'libjulia.dll'
>>> library_path = os.path.abspath(julia_dll)
>>> julia_library = ctypes.CDLL(library_path)
Traceback (most recent call last):
  File "<python-input-7>", line 1, in <module>
    julia_library = ctypes.CDLL(library_path)
  File "C:\WindowsTools\Python313\Lib\ctypes\ __init__.py", line 390, in __init__
    self._handle = _dlopen(self._name, mode)
                   ~~~~~~~ ^^^^^^^^^^^^^^^^^^
OSError: [WinError 193] %1 n’est pas une application Win32 valide
>>>

```

same code with python 64 bits and julia 64 bits works.

julia win32 downloaded from: [https://julialang-s3.julialang.org/bin/winnt/x86/1.11/julia-1.11.3-win32.zip](https://julialang-s3.julialang.org/bin/winnt/x86/1.11/julia-1.11.3-win32.zip)

Did I miss something ?

Thanks
