I believe the tools provided by the site statically like SQLite so no DLL is required. The DLL is provided as a courtesy to those who do not want to link their own apps statically. Not near a computer to confirm this, but I know for a fact that 32 / 64 bit DLLs are not interchangeable. See https://msdn.microsoft.com/en-us/library/windows/desktop/aa384231(v=vs.85).aspx
