Its this part that fails... always returns null

HMODULE h = cast(HMODULE) Runtime.loadLibrary(dllName);
if (h is null) {
    writeln("error loading");

I there any way to see why Runtime.loadLibrary is failing? It just returns null on error which is not very helpful.

You can probably use: core.sys.windows.winbase.GetLastError

That was helpful, error is:

ERROR_DLL_INIT_FAILED

1114 (0x45A)

A dynamic link library (DLL) initialization routine failed.

Thank you this helped lead me to the real error.
The problem was here

writeln("DLL_PROCESS_ATTACH");
Runtime.initialize();

Cant use writeln before Runtime.initialize
