If the cause of the problem remains unknown, you can try not
to rely on Windows to load the dependency DLLs, and load
them manually (before your mylib.dll) via (ffi-lib) calls.

If mylib.dll depends on some dep.dll, and dep.dll has
been already loaded prior to dep.dll, then you can be sure
than Windows will not load dep.dll from somewhere else
(where other dep.dll may exist and have wrong bitness)
