C++ DirectX 9 unresolved external symbol

Question

Yes I included all the libs but every time I run my program in x64 it gives me an unresolved symbol but works perfectly in x32??

Severity Code Description Project File Line Suppression State Error LNK2019 unresolved external symbol Direct3DCreate9Ex referenced in function "int cdecl DirectXInit(struct HWND *)" (?DirectXInit@@YAHPEAUHWND__@@@Z) DirectX Overlay D:\VSprojects\2020\Mygui\Garrysmod take 2\Overlay aimbot\DirectX.obj 1

Again, it is most likely not do to with an include because it works like a clock in x32.

With the legacy DirectX SDK, you have to set up distinct x86 vs. x64 library include paths:

In VC++ Directories for 32-bit configurations:

$(IncludePath);$(DXSDK_DIR)Include
$(LibraryPath);$(DXSDK_DIR)Lib\x86

In VC++ Directories for 64-bit configurations:

$(IncludePath);$(DXSDK_DIR)Include
$(LibraryPath);$(DXSDK_DIR)Lib\x64

See Microsoft Docs

For new projects you should be using Direct3D 11, and you do not need to use the legacy DirectX SDK at all.
