Packaging for HTML5 only brings up the documentation

So, I’ve been having a go at packaging for HTML5. I was able to get it to appear as a packaging option after following the documentation however when I try to package a project nothing happens except that the documentation appears in my browser. Have I done something wrong?

There was an error saying I had the wrong version of emenscripten installed that I hadn’t seen! Needs to be 1.25.

I HAVE THE same problem package android file.problem unsolve
