==================================

Do you have gksudo command installed on your system?

==================================

This issue is also reproduced in the following article:
Make A Bootable Windows 10 USB Install Stick On Linux With WinUSB Fork ~ Web Upd8: Ubuntu / Linux blog

====================================

I got same problem but solved now by
"sudo apt-get install gksu"
"gksudo winusbgui"
(i.e..type it without quotes)

Lin-Buo-Ren changed the title from "Installation failed !" in GUI but not in CLI to "Installation failed !" in GUI but not in CLI (/usr/bin/winusb: line 78: 18265 Terminated )

======================================================

Hi again, please use the latest revision in GitHub repo and see if it‘s still reproducible(it should be, as we never fixed the problem anyway).

=======================================================

I was encountered this issue right now, with windows 10.
I‘m on ubuntu 16.04 and WinUSB 1.0.11

I tried to run the installation anyway and it worked(I just ignored the error).

=====================================================

Hi, please use the latest revision in the repository (instead of latest released version) for reproducing the issue. We‘ve have changed a quite amount of code since 1.0.11

======================================================

I got similar problem and solve it!
I dont now why, but if you use GUI its not work. Use command line in way:
sudo winusb --format /path-to-ISO-file/filename.iso /dev/sdb (or other way to your flash)

=========================================================

The issue title already tell that CLI(command line interface) works.
This issue is about the GUI problem
