Error: Dynamic Linking Error: Win32 error 193 while binding to Eztwain3.dll library using nodejs ffi

Question

I successfully bound my nodejs to the 'TSCLIB.dll' using the ffi, but when I want to bind it to 'Eztwain3.dll', I always have "Error: Dynamic Linking Error: Win32 error 193".

C:\Users\dev\Desktop\nodeApp>node scan.js
C:\Users\dev\Desktop\nodeApp\node_modules\ffi\lib\dynamic_library.js:74
    throw new Error('Dynamic Linking Error: ' + err)
    ^

Error: Dynamic Linking Error: Win32 error 193

    at Function.Module.runMain (module.js:694:10)
    at startup (bootstrap_node.js:204:16)

The execution shown above appear when I'm trying to run this script.

const ffi = require('ffi');
const ref = require('ref');

    const platform = process.platform;
    var lib = null;

    if (platform === 'win32') {
        lib = 'Eztwain3.dll';
    } else {
        throw new Error('unsupported plateform for lib')
    }

    var instance = ffi.Library(lib, {

    });

I tried to execute the same script with 'TSCLIB.dll' and it run without exeption.
So, how can I call the 'Eztwain3.dll' library with node ffi?

I resolve my problem by changing the nodejs from 64bit to 32bit because my dll is 32 bit
