The process I went through is:

  1. Install the engines for 4.10.2 and 4.11P3 in the Epic Game Launcher.
  2. Install the latest (4.10.2) version of .
  3. Create a on a local drive.
  4. Right click on the uproject and switch the unreal engine version to 4.11P3 and then launch the editor.
  5. Check the “download maps on the fly (experimental)” option in the HTML5 category of the project settings.
  6. Package for HTML5 via the file menu (the development build setting is set by default).
    7)Launch HTML5LaunchHelper.exe and navigate to localhost:8000/TappyChicken.html
    8)The error messages mentioned in my main post should appear sometime during the “compiling” message.

I just tried running it on the 64-bit versions of firefox and chrome and it runs into the same errors.
