I'm trying to generate a responsive HTML5 output, but every time I try it says "Failed to generate responsive HTML5 output. See compilation output for details." It will say this on loop until Robohelp crashes. Compilation output just says to be sure I've selected a template (which I have done), and that an internal error has occurred.. I'm using the latest version of Robohelp 12. I have one book and 4 topics. Responsive HTML5 preprocessor 126.96.36.1994. Windows 10 64 bit.
