unable minify construct 2 my project is the problem

I can't export my project. I wanna make an exe files by exporting nw.js but doesn't work. can't minify, they ask me if I have java 64 bits and I have it. I've updated construct 2 to beta release 243 but does'nt work. I've used flappy bird project to test and that works, no minify problem. I don't want to share my project here. what should I modify on my project ?

The only plugin I'm using is from Spriter. I only use it to export from software spriter to construct 2 my sprite.

please help me I can't continue my project without it. I've tried so much things I don't understand why my project is not minified.

up. I really need help
