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());

listFilesToUpdate(filesToUpdate);

downloadFiles(filesToUpdate);
public List<DownloadFiles> checkForUpdates(List<DownloadFiles> allFiles) {
    allFiles.stream()
        .filter(file -> !hasFile(file.getFilename()) || !fileUpToDate(file))
        .collect(toList())

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());

  listFilesToUpdate(filesToUpdate);

  downloadFiles(filesToUpdate);
}

private static void downloadFiles(List<DownloadFiles> filesToUpdate) {
  filesToUpdate.stream()
      .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");
  filesToUpdate.stream()
      .forEach(System.out::println);
}

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

private static boolean isFileUpToDate(DownloadFiles file) {
  try (InputStream is = new URL(file.URL).openStream()) {
    return DigestUtils.md5Hex(new FileInputStream(Settings.saveDir))
        .equalsIgnoreCase(DigestUtils.md5Hex(is));
  } 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:
        self.headers.pop('authorization')
    return orig_urlopen(self, method, url, redirect, **kw)


urllib3.poolmanager.PoolManager.urlopen = new_urlopen

# 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'])

        bar.update(zz)

    # 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:
        app_update.progress_hooks.append(cb)
        if app_update.download():
            if isinstance(app_update, AppUpdate):
                app_update.extract_restart()
                return True
            else:
                app_update.extract()
                return True
    return False


def main():
    print('Current version is ', ClientConfig.APP_VERSION)
    if check_for_update():

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) => {
    console.log("update-downloaded");
    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
            }
        }
    }
}
