Huge difference in delta file size for x64

Hi, I had been creating the installer for both the windows ia32 and x64 arch. For some reasons the delta file generated for my x64 architecture is too big.

For me: size of V1 ia32 = 43mb, v1 x64 = 96mb

This huge difference itself weird for me of same code base.

On V2 delta ia32 = 22kb, v2 delta x64 = 50mb

Can someone help me out?

var electronInstaller = require('electron-winstaller');

resultPromise =   electronInstaller.createWindowsInstaller({
      appDirectory: applicationDirectory,
      outputDirectory: outDirectory,
      authors: AuthurName,
      setupExe: setupExeName,
      noMsi: true,
      exe: exeName,
      remoteReleases:releaseURL 
  });

resultPromise.then(() => console.log("Installer created for "+ packageName + ' '+ channel +' '+platform),
                  (e) => console.log(`No dice: ${e.message}`));

@paulcbetts It was my problem… I was packaging the app in same folder which results in increase in the size of the package of x64 which packed after ia32. This ultimately chains for the problem for huge diff and stuffs. Sorry for disturb you guys… Appreciate your immediate response.

@mzmousa I package the app in the same build folder which creates the packaged app for ia32 inside my build folder itself… that y on packaging the x64 the file size got doubled.
