Browser version:

This site has a minimum browser requirement, outlined below. Critical functions of the site will not work properly if this requirement is not met by your computer. Fortunately, browser upgrades are freely available for download. In many cases, your local IT staff will have to do this for you.

Minimum Browser Version:

This site works with most major modern browsers. Please make sure you are using a recently updated version of your browser to assure security and compatibility. If you are using Internet Explorer, please use version 9 or higher. To check what browser version you are using and to update to the latest version, visit

Note: Specific courses may work better in Internet Explorer and you will be notified during the course launch process.

Flash Plugin:

The Macromedia Flash browser plug-in is necessary to view much of the course content for this site. Most users (more than 95%) have this plug-in pre-installed on their computer at the time of purchase. A few others will have to download it from the Macromedia website.

It is a brief download, and costs nothing. If the following instructions do not work for you, it may be necessary to have your local IT staff perform the installation.

  1. Go to the following link:
  2. Make sure the box "Also install...Yahoo Toolbar" is not checked! The Yahoo toolbar has a pop-up window blocker that will interfere with this site.
  3. Press the "Install Now" button
  4. The installation will not take longer than a few minutes, and perhaps much less. You should follow the instructions on Macromedia's download page to complete the installation. For example, "You may need to click the gold bar at the top of the browser window to allow the install."
  5. When the Flash installation is complete (it will say so), close down all your browser windows, restart the browser, and return to this site.

To Enable or Disable your Browser's Popup Blocker:

To properly access this site, you will either need to have any pop-up blockers on your computer disabled or modify them to accept pop-up windows from *

Note that you may have more than one of these blockers installed on your system. They are commonly found in free browser toolbars (for example, the MSN toolbar), and sometimes in security applications like Norton. While we cannot show how to disable all pop-up blockers, we have instructions below for disabling three of the most common: the Internet Explorer blocker, and those found on the Google and Yahoo toolbars.

  1. The Internet Explorer Pop-up blocker. For users of Windows XP service pack 2 or Vista, this blocker is built into the menus of Internet Explorer itself. You can see if you have this blocker by clicking on the “Tools” menu as indicated, and looking to see if there is a line that reads “Pop-up Blocker”. If it’s not there, then you don’t have this blocker. If it is there, go to the right as indicated in the screenshot and click the “Turn Off Pop-Up Blocker” option. Then try again to enter this site.

  2. The Google Toolbar Pop-up blocker . If you see this toolbar near the top of your browser, navigate your browser to this site and click on the button that says something like "5 blocked" to disable pop-up blocking for this site. It should now show "Popups okay" (indicated in the screenshot below). Then try again to enter this site.

  3. The Yahoo Toolbar Pop-up blocker . If you see this toolbar near the top of your browser, click on the Pop-up blocker toolbar icon as indicated and uncheck the line labeled “Enable Pop-Up Blocker”. Then try again to enter this site.

If this doesn’t solve the problem, and you are still denied access to this site because of a persistent pop-up blocker, we recommend you contact a local tech support staff in your office and ask them to help you disable any further pop-up window blocking security software.

Enabling ActiveX:

ActiveX is a technology used within Internet Explorer which allows the browser to display some of the dynamic content within web pages. Some of the other technologies within Internet Explorer (for example, the Flash plugin) rely on ActiveX in order to function properly themselves, so it is important to verify ActiveX is enabled in your browser.  To do so:

  1. Click Internet Explorer's Tools menu and select the Internet Options... menu item.
  2. Click the Security tab at the top of the Internet Options window which opens.
  3. Click the icon of a checkmark within a green circle labeled Trusted sites and then click the Custom Level... button toward the bottom of the page.
  4. In the Security Settings window which opens, scroll down to the second main section, "ActiveX controls and plug-ins"
  5. Verify the 7 settings in this section are configured as follows:
    • Automatic prompting for ActiveX controls: Enable
    • Binary and script behaviors: Enable
    • Download signed ActiveX controls: Enable
    • Download unsigned ActiveX controls: Prompt
    • Initialize and script ActiveX controls not marked as safe: Prompt
    • Run ActiveX controls and plug-ins: Enable
    • Script ActiveX controls marked safe for scripting: Enable
  6. Press OK to return to the Internet Options window.
  7. If you have not already defined as a Trusted Site within your browser, do so now by following the directions for the JavaScript Settings for Internet Explorer, above.
