When I try to delete those two files in package.nw directly, both 7Zip and Window's native zip tool don't allow me to - Googling suggests that the zip's headers aren't correct. So instead, I've tried extracting all the files, replacing style.css & package.json, then recompressing as package.nw - but when I run my executable, all I get is a NW.JS splash screen. I get the same problem if I export the sample "Construct 3 - Invisible Window" project. Is there some specific version of nw.js I need to use or some specific settings in Construct's export dialogue?
