A user is getting this error when accessing a CPA Australia webpage, and I've been unable to determine exactly what is causing the error.  

This is the error:

"Webpage error details

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET CLR 1.1.4322; .NET4.0C; .NET4.0E; Tablet PC 2.0)

function initialise()
{
      courseStartTime = new Date().getTime();

      if (top.window.opener.flashInstalled == 1) <<----------------LOOK HERE-----------------------
            flashInstalled = true;

      LMSPresent = top.window.opener.LMSPresent;
      preloadImages();
      findBaseURL();
      if (web)
      {
            if (!LMSPresent)
            {
                  dbTracking = top.window.opener.dbTracking;
                  loginName = top.window.opener.loginName;
            }
            else
            {
                  trackingData = top.window.opener.trackingData;
            }
      }

      continueInit()
}

It's stating that the sub-sub-sub-sub object "flashInstalled" was never given a value prior to that function executing. It needs to be defined somewhere prior to that code executing.

Here's the information on the browser your user is getting:
Internet Explorer 8.0 on Windows NT 6.1 (Windows 7) with Microsoft dot NET installed, versions 2.0.50727, 3.5.30729, 3.0.30729 and 1.1.4322, as well as InfoPath v.3 MS Office Component, Microsoft Office Live Meeting, Microsoft Tablet Service v.2.0 and Microsoft-Windows-Security-Licensing-SLCC component.

Now, if he's the only person getting it, he could have MS Office installed with Debugging turned on in his browser, which would trigger debugging attempts at websites he attempts to visit. Most browsers don't have this feature enabled by default,  unless you install something like Office 2003 Professional or Enterprise that has an HTML editor or code debugger built in. This feature can be turned off in the Internet Explorer Advanced Settings. He will need to:

Open IE -> Click "Tools" -> Click "Internet Options" -> Go to "Advanced" (tab) -> then the 4th Item in "Browsing" should say "Disable Script Debugging" ... make sure that is CHECKED to disable it ... hope that fixes it.
