I have the same problem with electron-packager on Win 10:

Same resut with a new app create with the electron-quick-start as a base

Packaging app for platform win32 ia32 using electron v2.0.6
Unhandled rejection Error: Invalid package C:\Users\suppo\AppData\Local\Temp\electron-packager\win32-ia32-template\resources\default_app.asar at invalidArchiveError (ELECTRON_ASAR.js:153:19) at Object.module.(anonymous function) [as open] (ELECTRON_ASAR.js:209:16) at WriteStream.open (fs.js:2158:6) at new WriteStream (fs.js:2144:10) at Object.fs.createWriteStream (fs.js:2106:10) at writeStream (C:\Electron\open-grid\node_modules\extract-zip\index.js:175:36) at C:\Electron\open-grid\node_modules\extract-zip\index.js:172:18 at C:\Electron\open-grid\node_modules\yauzl\index.js:439:7 at C:\Electron\open-grid\node_modules\yauzl\index.js:473:5 at C:\Electron\open-grid\node_modules\fd-slicer\index.js:32:7 at FSReqWrap.wrapper [as oncomplete] (fs.js:658:17)

But If i extract manualy the package
C:\Users\suppo\AppData\Local\electron\Cache\electron-v2.0.0-win32-ia32.zip
into
C:\Users\suppo\AppData\Local\Temp\electron-packager

A new error is show :

`Unhandled rejection Error: ENOTEMPTY: directory not empty, rmdir 'C:\Users\suppo\AppData\Local\Temp\electron-packager\win32-ia32-template\resources'
electron-quick-start.zip

`

@LudiscapeXApi I cannot reproduce this on Linux with your zip file. The packaged app runs normally.

Why are you specifying prune: false?

[LudiscapeXApi]

I cannot reproduce this on Ubuntu 18 too. Only on Win 10.
prune false/true same result :
Packaging app for platform win32 ia32 using electron v2.0.6 Unhandled rejection Error: Invalid package C:\Users\suppo\AppData\Local\Temp\electron-packager\win32-ia32-template\resources\default_app.asar at invalidArchiveError (ELECTRON_ASAR.js:153:19) at Object.module.(anonymous function) [as open] (ELECTRON_ASAR.js:209:16)
and next :
Unhandled rejection Error: ENOTEMPTY: directory not empty, rmdir C:\Users\suppo\AppData\Local\Temp\electron-packager\win32-ia32-template\resources

[LudiscapeXApi]

I found a solution :
Turn off the asar functionality and then run it.
process.noAsar = true;

@LudiscapeXApi @malept thank you guys.I set process.noAsar = true.The packaged app runs normally.
