Can't package my project on HTML 5 (all prerequies but options missing / ...)

Hi folks !

I have problem (since days/weeks) to package my game on html5.
I follow this steps A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums

I am on UE 4.15.3

I have :

  • Emscripten 1.37.1
  • Python 2.7.13
  • I Checked Environment Var
  • I Installed Chromium and Nightly (both 64bits)
  • Add vars (sdk path) on *\Program Files\Epic Games\UE_4.15\Engine\Config\HTML5\HTML5Engine.ini

And :

  • The package proceed correctly, but when I open my project-shipping.html :
    • with the HTML5LaunchHelper.exe, have a (project.data.js) download / refresh problem (“not serving” in loop)
    • directly the .html with Nightly, I have a download bar but nothing happens
      **- The weird thing is I don’t have the SDK PATH options on my project options, like this screenshot

(not mine)**

I’m really lost, I didn’t know it was so complicated to publish my game on browser.
If anybody have ideas… ^^"
