This is /the/ classical 32-versus-64-bit mismatch error. Most likely,
once of the DLLs that your DLL in turn depends on is loading in the
wrong flavor. Bitness is the most likely suspect, but you could also
conceivably have a version compiled for a different target architecture.
To decipher this and future error codes, look them up in winerror.h in
your Windows SDK. Then go grepping through msdn.microsoft.com with the
name of the constant. This one is ERROR_BAD_EXE_FORMAT.
You probably should take Racket out of the loop here. Write a four-line
C program that explicitly tries to load your DLL. Something like
#include <windows.h>
HANDLE h = LoadLibraryA("mydll.dll");
if (NULL == h) printf("ERROR %lu\n", GetLastError());
else { FreeLibrary(h); printf("Great success\n"); }
Compile that fragment in the same bitness of your Racket installation on
Windows, and use it to ensure that your DLL itself can resolve all its
dependencies. Once your DLL can pass this test, feed it to Racket.
