Does that help I am not entirely sure that I understood your question, but maybe you want to do sth like:
code :
//in Launcher

EnumSet<DownloadFileS> filesToUpdate = checkForUpdates(DownloadFiles.values());


public List<DownloadFiles> checkForUpdates(List<DownloadFiles> allFiles) {
        .filter(file -> !hasFile(file.getFilename()) || !fileUpToDate(file))

private boolean isFileUpToDate(DownloadFiles file) {
    return DigestUtils.md5Hex(new FileInputStream(Settings.saveDir))
       .equalsIgnoreCase(DigestUtils.md5Hex(new URL(downloadUrl).openStream())));
public static void main(String[] args) {
  List<DownloadFiles> filesToUpdate = checkForUpdates(DownloadFiles.values());



private static void downloadFiles(List<DownloadFiles> filesToUpdate) {
      .forEach(file -> downloadFile(file));

private static void downloadFile(DownloadFiles file) {
  try {
    URL website = new URL(file.URL);
    ReadableByteChannel rbc = Channels.newChannel(website.openStream());
    FileOutputStream fos = new FileOutputStream(file.filename);
    fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
  } catch (IOException e) {
    throw new RuntimeException(e);

private static void listFilesToUpdate(List<DownloadFiles> filesToUpdate) {
  System.out.println("Following files will be updated");

public static List<DownloadFiles> checkForUpdates(DownloadFiles[] allFiles) {
  return Arrays.asList(allFiles).stream()
      .filter(file -> !hasFile(file.filename) || !isFileUpToDate(file))

private static boolean isFileUpToDate(DownloadFiles file) {
  try (InputStream is = new URL(file.URL).openStream()) {
    return DigestUtils.md5Hex(new FileInputStream(Settings.saveDir))
  } catch (IOException e) {
    throw new RuntimeException(e);

This might help you It appears that you cannot do an update on a DOM id element that is inside a form tag in ie. Has anyone found a way around this? My code works fine when I move it outside the form tag, and also when I just comment out the form tag and don't move the DOM element.

I wish this help you Without knowing any additional info, the absolute easiest and fastest way I can think of (if all of the computers that have these applications are on the same network) is to simply write a batch file that checks for the existence of each application on the local machine, and if it finds it, it pulls an "update" batch file for that application from a central location and runs it (then continue on for the other applications).
Something like this:
code :

SET CentralLoc=\\CentralServer\Updates


IF EXIST C:\CompanyApplications\Application1 (  
    COPY %CentralLoc%\UpdateApplication1.bat .\
    call .\UpdateApplication1.bat

around this issue Few issues with the code.
You shouldn't have debugging log enabled, else that would hamper with the progress bar You didn't start the progress bar You had a error in progress bar callback status.the_dwad The code may not run well in a IDE as progressbar has some issues with it, so you should run it in a terminal
code :
import urllib3.poolmanager

orig_urlopen = urllib3.poolmanager.PoolManager.urlopen

def new_urlopen(self, method, url, redirect=True, **kw):
    if "s3.amazonaws.com" in url and 'authorization' in self.headers:
    return orig_urlopen(self, method, url, redirect, **kw)

urllib3.poolmanager.PoolManager.urlopen = new_urlopen

import logging

# logging.basicConfig(level=logging.DEBUG)

import http.client as http_client

# http_client.HTTPConnection.debuglevel = 1

import logging
from selenium import webdriver

# logging.basicConfig(level=logging.DEBUG)

from client_config import ClientConfig
from pyupdater.client import Client, AppUpdate

import progressbar
import sys

bar = None

def check_for_update():

    def cb(status):
        global bar

        if bar is None:
            bar = progressbar.ProgressBar(widgets=[progressbar.Percentage(), progressbar.Bar()], fd=sys.stdout).start()
        zz = float(status['percent_complete'])


    # sys.stdout = open(os.devnull, 'w')

    client = Client(ClientConfig(), refresh=True,
                    headers={'basic_auth': 'brofewfefwefewef:EKAXsWkdt5H6yJEmtexN'})

    client.platform = "win"
    app_update = client.update_check(ClientConfig.APP_NAME, ClientConfig.APP_VERSION, channel='stable')
    if app_update is not None:
        if app_update.download():
            if isinstance(app_update, AppUpdate):
                return True
                return True
    return False

def main():
    print('Current version is ', ClientConfig.APP_VERSION)
    if check_for_update():
        print('there\'s a new update :D')
    driver = webdriver.Firefox()

Electron auto updater downloading multiple builds

Electron auto updater downloading multiple builds

Hope this helps Both issue has been resolved in electron-builder: 2.17.0 and electron-updater: 2.23.0
After debugging so much in code. I found a solution to both of my problems.
code :
return (0, _lodash().default)(_this.versionInfo, versionInfo) && (0, _lodash().default)(_this.fileInfo, fileInfo) && (yield (0, _fsExtraP().pathExists)(updateFile));
autoUpdater.on('update-downloaded', async (event) => {
    let download_exe_obj = {path: autoUpdater.downloadedUpdateHelper._file, version: event.version};
    await update_downloaded_exe_data(download_exe_obj);// save download_exe_obj somewhere so that it can be used later on
const app = electron.app; //to get version and details from package.json
function createWindow() {
    mainWindow = new BrowserWindow({ width: 800, height: 600 })
    let available_exe_json = await get_downloaded_exe_data(); //get json from where you have saved
    if(available_exe_json != ''){
        let available_exe_obj = JSON.parse(available_exe_json);
        if (available_exe_obj.version != '' && available_exe_obj.version.toString() == app.getVersion().toString()) {
            //remove old installer
            if (available_exe_obj.path != '' && await fs.existsSync(available_exe_obj.path)) {
              await fs.unlinkSync(available_exe_obj.path);
              await update_downloaded_exe_data('');//update with blank where you have saved previous data
