    3. Click the option that you want. Make sure Install updates automatically is not turned off. PC users running Windows XP or an earlier version must upgrade to Windows Vista SP2, Windows 7 or Windows 8.

    To turn on Automatic Updates in Windows 8 and Windows 8.1:

    1. Open Windows Update by swiping in from the right edge of the screen (or, if you're using a mouse, by pointing to the lower-right corner of the screen and moving the mouse pointer up), then click Settings.
    2. Click Change PC settings, and then click Update and recovery.
    3. Click Choose how updates get installed.
    4. Under Important updates, select the option that you want.
    5. Under Recommended updates, select the Give me recommended updates the same way I receive important updates check box, and then click Apply.
  • Mac users:

    Updating your system software regularly by running Software Update... from the Apple menu. Mac users who are still running 10.6 or earlier versions of Mac OSX should upgrade to Snow Leopard (10.7) or a newer version.

How do I install required plug-ins?

Some content within Learning Central courses may require the installation of third-party plug-ins such as Adobe Flash, Windows Media Player, RealPlayer, and many others. In each case there should be a notification and a link informing you that you need to install a new plug-in.

The table below contains a list of common third-party plug-ins. You can download them FREE, directly from each software maker's website. Please be careful that you only install trusted plug-ins that are necessary for your course content and ensure that you have the compatible version of each plug-in, or you may experience problems.


Mozilla Firefox If you have a newer or older browser version that the current Learning Central does not support, you can uninstall your web browser by following the guides below, and then download a supported version and install it on your computer. Download Firefox (ESR) or a latest version for Windows and Mac OSX
Google Chrome If you have a newer or older browser version that the current Learning Central does not support, you can uninstall your web browser by following the guides below, and then download a supported version and install it on your computer. Download Chrome for Windows or Chrome for Mac OSX
Internet Explorer If you have a newer or older browser version that the current Learning Central does not support, you can turn it off or uninstall its update by following the guides below. Download IE 10 or IE 11 for Windows
Safari Download 6, or 7 for Mac OSX
Oracle Java

Java is free software by the Sun Microsystems Corporation that is used to display some multimedia in a browser. Learning Central makes use of Java content for many of its elements.

PC users choose "Free Java Download"; you need "Java Runtime Environment" or "Java for Windows" version 7. Don't be seduced into installing the Yahoo Toolbar at the same time.

Mac users: Apple has changed the way it includes Java in Mac OS. Java is not pre-installed with Mac OS X 10.7 (Lion) and above. To get the latest Java 7 from Oracle, you will need Mac OS X 10.7.3 and above. Be aware that you are unable to use Chrome with Java 7 on Mac. Chrome is a 32-bit browser. A 64-bit browser (e.g., Safari and Firefox) is required to run Java 7 on Mac OS X. 32-bit browsers such as Chrome do not support Java 7 on the Mac platform.

Test your browser for the Java plug-in at the Java website.

Adobe Flash Player

The Adobe Flash Player is free software from the Adobe company that is used in many webpages to display animation, video and/or audio. The most current version of the Flash player is the best choice. If you view webpages with video, games or animation you likely already have the Flash player installed. Many courses in Learning Central include materials that use the Flash player. Follow the instructions on the Adobe Flash Player download page to download or upgrade your Flash Player.

For more information on current versions visit the Adobe website.

A university imaged PC should have Flash Player plug-in installed by default.

Adobe Reader

The Adobe Reader is free software from the Adobe company that is used in many webpages to display pdf (short for Portable Document Format) files. It is best to use the most current version of the Adobe Reader.

PC users: Learning Central recommends Adobe Reader version 10 or later.

Mac users: The built in PDF viewing is adequate for most purposes.

Third-Party PDF Plug-ins
(Mac users only)

Adobe has released an advisory regarding issues with viewing PDF files on Mozilla Firefox and Apple Safari browsers in Mac OS X (10.6 and 10.7).

In Learning Central, if you have experienced a problem of viewing PDF files and clicking on the "Missing Plug-in" returns no results, you need to click the "Install Missing Plugin" button on the warning message bar and install the PDF Viewer for Mac OSX, Once installed, restart the web browser, and it should be activated.

Alternatively, the Schubert IT PDF plugin is one recommended by the Blackboard user community, and is free for educational use. Once installed, restart the web browser, and it should be activated.

RealPlayer

Learning Central no longer recommends installing RealPlayer.

If you want to install it, choose the "RealPlayer" link on the left column to "Download Free RealPlayer" and you do not need the "RealPlayer with SuperPass" version. Beware that for some platforms both versions are downloaded from the same link, but then you are offered a setup option; you need the free "basic setup" version, not the "premium" or "free trial" version.

Windows Media Player

PC users: WMP is normally installed automatically as part of Windows Update. We recommend WMP 11 or WMP 12.

Mac users: Learning Central recommends installing Windows Media® Components for QuickTime from Flip4Mac rather than WMP.

Apple QuickTime

After clicking, select the link to download the FREE player. We recommend QuickTime 7.7 or later for both Mac and PC.

A university imaged PC should have QuickTime™ installed by default.

Apple iTunes A proprietary digital media player application, is used for playing and organising digital music and video files.
Natural Reader A free screen reading application that allows you to listen to any text on your computer.
OpenOffice A free Word Processing application.
Office Online File Converters A Microsoft application that helps you to share your Microsoft Office files with people who have different versions of Office applications, or even with people who don't have Office installed.

According to your computer operating system and web browser, you can get more information from different sections above. If the content is unable to help you any further or your exact problem is not listed, please follow the instructions under the "More help" section.

How to allow mixed content

SSL secure technology is installed in Learning Central. A secure connection, recognisable by the HTTPS in the URL, means that the information being exchanged between Learning Central and your browser is being encrypted and adding an additional layer of security onto the environment.

Users may find themselves getting an annoying number of messages stating like:

"This page contains both secure and non-secure items. Do you want to display the non-secure items?"

This notice means that the webpage is trying to display both secure and non-secure content. This is called "mixed content". Non-secure items are usually images or icons created by content contributors which are being stored on a non-SSL host.

If you find this bothersome, you may temporarily have your browser allow all mixed content by following the instructions "SSL and Learning Central". After allowing mixed content, you will see webpages with both HTTPS and non-HTTPS (http protocol) content and no warning messages.

SSL and Learning Central

If you create a link in Learning Central to a non-SSL site (i.e., one that begins with http:// rather than https://), Internet Explorer 10 tries to protect you from potentially harmful third-party websites by asking, "Only secure content is displayed". Internet Explorer blocks non-secure content by default and is set to prompt you when this is happening. The best suggestion for instructors is to modify an External Link to be opened in a new window rather than in the Learning Central frame. However, you are able to change this setting and allow the browser to temporarily display non-secure content without asking by following steps below.

  1. Once your browser is open, click Tools menu icon and then click Internet options.
  2. Select the Security tab.
  3. Click the Custom Level... button.
  4. In the Settings box, scroll down to the Miscellaneous section and choose Enable or Prompt for "Display mixed content".
  5. Click the OK button to close the Security Settings window.
  6. Click the OK button to close the Internet Options window.

Please notice that when this setting is set to Enable, Internet Explorer does not prompt you with the "Only secure content is displayed" message even if the webpage is using non-secure elements.

How to allow mixed content

SSL secure technology is installed in Learning Central. A secure connection, recognisable by the HTTPS in the URL, means that the information being exchanged between Learning Central and your browser is being encrypted and adding an additional layer of security onto the environment.

Users might find themselves getting messages stating: "You have requested an encrypted page that contains some unencrypted information." This warning means that the webpage is trying to display both secure and non-secure content. This is called "mixed content". Non-secure items are usually images or icons created by content contributors which are being stored on a non-SSL host.

In Firefox 23 and above, the Mixed Content will be blocked by default. The Mixed Content Blocker shows as a shield icon ahead of the URL address in the Location Bar (or address bar) if a webpage you visit contains Mixed Content.

You can enable the feature (see steps below) but if you encounter a page that breaks because a mixed content resource is blocked, the only way to fix the page and load the insecure content is to turn the feature off. We do not suggest users to change the feature if this is not applicable to you.

  1. Once your browser is open, type about:config in the Location Bar (or address bar) and press Enter key.
  2. Find the Preference Name "security.mixed_content.block_active_content" and turn it to True by double clicking on it.
  3. Find the Preference Name "security.mixed_content.block_display_content" and turn it to True by double clicking on it.
