How to run web IRC Client in node-webkit on Windows?

Question

I am trying to run a web IRC client, The Lounge, as a regular Windows IRC Client.

But after packing into a .nw file, it does not work:

git clone https://github.com/thelounge/lounge.git
cd lounge
npm install
NODE_ENV=production npm run build
zip -r ../lounge.zip *
mv lounge.zip to lounge.nw

and then on Windows:

copy /b nw.exe+app.nw app.exe
