NB:
  • If you PASS all the checks, you should be able to use the main features of Learning Central.
  • If you have a message of green "compatible" or "certified", you should be able to use the main features of Learning Central. "Certified" means fully tested and supported. "Compatible" means partially tested before release but should function properly.
  • If you have a message of red "unsupported" or "incompatible", your web browser either not supported by the vender or not tested. You should check your operating system and web browser version regarding to the warning messages (see the "Read it first" section).
  • If you receive a red or yellow warning message in the table above, you need to check if Learning Central requires any plug-ins or if any relevant application needs to be updated (see the "Read it first" section). If it is not applicable, ignore the warning message.
  • If your course in Learning Central requires plug-ins or an application needs to be updated, follow the instructions under the "Read it first" section.
  • With Learning Central, your browser must have Java, JavaScript, third-party cookies and ActiveX Controls enabled, and pop-up blocker disabled. See details in a section above in terms of your computer operating system and web browser.
  • If you can't view the information in the table above, check if you have a warning message on the browser information bar (see an example below). You need to allow the blocked content.

    For example, Internet Explorer 8 users may see this message:
    Security Warning on IE8


    (1) Click the right mouse button, and select the first option Allow Blocked Content...
    Allow Blocked Content in IE8

    (2) When you see the pop-up Security Warning window, click Yes.
    Active Blocked Content in IE8

    (3) Now you should be able to see your computer settings in the table above.

  • As a Google Chrome user, if you can't view your Java information in the table above, check if you have a warning message on the browser information bar (see an example below). You need to allow Java runs on this website.

    Java Warning on Chrome

    (1) Click the "Always run on this site" button. Then you should see the warning message bar has disappeared.

    (2) Refresh the webpage again. You can refresh the webpage by clicking "Reload" icon next to the URL address bar or by pressing hotkeys: F5 (for Firefox, Internet Explorer, Chrome); Command + R (for Safari and Chrome with Mac OSX).

If you complete the checks and install necessary plug-ins and updates, YOU ARE DONE!

Users should access to Learning Central by a university networking PC or a secure computer. A university imaged PC displays your workstation information through a "computer icon" on the taskbar (see below).

  • Mac users:

    Updating your system software regularly by running Software Update... from the Apple menu. Mac users who are still running 10.5 or earlier versions of Mac OSX should upgrade to Leopard (10.6) or Snow Leopard (10.7).

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.

For Mac users, please notice that Safari [version 5.1] and Mac OSX software updates [OSX 10.6.8 and OSX 10.7] have removed the download/viewing capability of PDF documents using Mozilla Firefox and Apple Safari browsers. The workaround for Safari and Firefox is to install a third-party PDF plug-in (see the Third-Party PDF Plug-ins section in the table below).


Mozilla Firefox Download Firefox (ESR) or a latest version for Windows and Mac OSX
Internet Explorer Download IE 8 or IE 9 or IE 10 for Windows
Safari Download Safari 4, 5, or 5.1 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 probably want "Java Runtime Environment" or "Java for Windows" version 7. Don't be seduced into installing the Yahoo Toolbar at the same time.

Mac users: Snow Leopard (10.6) includes the preferred Java 1.6. Recently, Apple changed the way it includes Java in Mac OS, and with Lion (10.7), Java is no longer preinstalled. It is now an optional install that you must select. Download Java by Apple website or Java website for Mac OSX 10.7.

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.

You may follow the university guide to installing Adobe Acrobat Reader on a University computer.

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 link 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

Internet Explorer 8 users:

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 8 will try to protect you from potentially harmful third-party websites by asking, "Do you only want to display content that is displayed securely". If you answer Yes (by default) to this question, then Internet Explorer 8 will NOT display non-secure content. That is, clicking Yes tells Internet Explorer to NOT display the pages you have linked to. Therefore, if you see the security message, you should choose No button.

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.

Internet Explorer 9 users:

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 9 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 and select Internet Options.
  2. Select the Security tab.

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.

Firefox 18, 19 and 20 do not provide the Mixed Content Blocker UI and a feature of controlling content loaded via an unencrypted connection is disabled by default. 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.
