Excel Help Examples Displays Blank

Question

From what i can tell is that Excel help is using the Microsoft Excel Services REST api with javascript
http://msdn.microsoft.com/en-us/library/office/hh315812(v=office.14).aspx
We are having an issue where users cannot see any of the excel help examples IE: Sum example.
Environment
Windows 7 (64bit) + Office 2010 Standard (32bit) + Internet Explorer 8 (Both versions installed but assuming that the program is using 32bit API's).
We have used an unrestricted proxy and this issue is still apparant.
When we upgrade the Internet explorer to IE9 it seems to work, however i cannot find anywhere online from microsoft that this functionality is not supported in IE8.
I have looked for the js files as described (Minified .js files for the JavaScript object model are installed
in the %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\14\TEMPLATE\LAYOUTS directory. The name of the file is EwaMoss.js.)  
and i am unable to locate them on the local computer.
Can anyone help please?

Answer 1

as i said this is the excel help functions within microsoft office 2010
here is the code.
var fileToken = "SD7274120315C4F6FB!458/8247236622081652475/t=0&s=0&v=!ANm1tDqSNAE49SE";
              // run the Excel load handler on page load
              if (window.attachEvent)
              window.attachEvent("onload", loadEwaOnPageLoad);
              else
              window.addEventListener("DOMContentLoaded", loadEwaOnPageLoad, false);
              function loadEwaOnPageLoad()
              // grab some references
              var frame = document.getElementById('cntXLWA-2042510967');
              var frameDoc = frame.contentWindow.document;
              // set some style
              frame.style.width = "100%";
              frame.style.height = "346px";
              frameDoc.body.setAttribute('style', 'margin:0; padding:0');
              // create the div
              var div = frameDoc.createElement('div');
              div.setAttribute('style', 'height: 100%; width: 100%');
              div.setAttribute('id', 'cntIFrameDiv');
              frameDoc.body.appendChild(div);
              // load the script element
              var se = frameDoc.createElement('script');
              se.setAttribute('type', 'text/javascript');
              se.src = 'http://r.office.microsoft.com/r/rlidExcelWLJS?v=1&kip=1';
              var callback = function() {
              if (se.readyState) se.onreadystatechange = null;
              else se.onload = se.onerror = null;
              var props = {
              uiOptions:
              selectedCell: "'Sheet1'!A1"
              interactivityOptions: { }
              // grab the Ewa reference once the script is loaded…
              window['Ewa']= frame.contentWindow ['Ewa'];
              Ewa.EwaControl.loadEwaAsync(fileToken, 'cntIFrameDiv', props, onEwaLoaded);
              if (se.readyState)
              se.onreadystatechange = function() {
              if (se.readyState === 'loaded' || se.readyState === 'complete')
              callback();
              else
              se.onload = se.onerror = callback;
              frameDoc.getElementsByTagName('head')[0].appendChild(se);
Even in the code it indicates that it uses this API.
 * This code uses the Microsoft Office Excel Javascript object model to programmatically insert the
              * Excel Web App into a div with id=myExcelDiv. The full API is documented at
              * http://msdn.microsoft.com/en-us/library/hh315812.aspx. There you can find out how to programmatically get
              * values from your Excel file and how to use the rest of the object model.
Can anyone confirm what pre-requesits this code requires on the users end ?
