Add alert based on user's browsers

How about detecting it within the HTML file using a Javascript?
Is there a reason why you need an LMS to detect MSIE browser?

Thanks Daniel

We've created all mandatory courses in HTML5 only.  But when users with IE as their default launch the course, they cannot understand why the content won't function.  My users are customer service specialists so aren't always aware that the problem relates to the browser they're using.  I'm hoping that by adding an alert when IE is detected, it will remind why it's not working.  

I've attempted to add this to the player.js document in the Program Files:

// Unsupported Browser

if (navigator.userAgent.indexOf('MSIE')>0) {

    document.write('You have launched this course via the Internet Explorer browser.  This means that the content will not function effectively.  Find out how to open  each and every time via the Chrome browser  <a href='http://genie/Interact/Pages/Content/Document.aspx?id=33351> please click here'</a>);

};

But this doesn't appear to be working.  Any obvious reasons why it's not?

The code below detects the browser, you can insert it as a trigger and then have the if statement set a Storyline variable and do whatever you want with that. Let me know if you need any help.

  // Opera 8.0+
 var isOpera = (!!window.opr && !!opr.addons) || !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;

 // Firefox 1.0+
 var isFirefox = typeof InstallTrigger !== 'undefined';

 // Safari 3.0+ "[object HTMLElementConstructor]" 
 var isSafari = /constructor/i.test(window.HTMLElement) || (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || (typeof safari !== 'undefined' && safari.pushNotification));

 // Internet Explorer 6-11
 var isIE = /*@cc_on!@*/false || !!document.documentMode;

 // Edge 20+
 var isEdge = !isIE && !!window.StyleMedia;

 // Chrome 1+
 var isChrome = !!window.chrome && !!window.chrome.webstore;

 // Blink engine detection
 var isBlink = (isChrome || isOpera) && !!window.CSS;

 if (isIE == true){

 // User is using IE, do something here

 }

Thanks Michael

Do I need to make any changes to the imsmanifest as well?  When users launch the content via IE, they often get the grey screen...which I'm presuming is one of the blank.html files.  Am I making the wrong assumption?

I'm not sure. Have you tried running the course (or a copy of it) with debugging turned on? You may want to do this with a copy so that your users don't see the debugging window. This might give you more of an idea of what the problem is and what files are being displayed. What LMS are you using?
