System Requirements

The Read Arabic! lessons have been tested and verified to function in the following environments:

  • Windows XP and 2000 with
    • Internet Explorer 6, 7, and 8
    • Firefox 3
  • Mac OS X with
    • Firefox 3

Your browser will use the first font it finds available on your computer. If your computer is not set up to display Arabic text, you will need to download and install Arabic font support. For enhanced readability, you may wish to install the NFLC's KacstBook font on your system. This installation requires administrator privileges. If you do not have administrative access to your computer, ask your system administrator for assistance.

Installing KacstBook Font

  1. Download and save Kacstbook NFLC.ttf to a temporary location on your hard drive.
  2. Go to Start > Settings > Control Panel and open the Fonts folder.
  3. Drag and drop the file into the newly opened window.
  4. Launch a Read Arabic! lesson to verify that Arabic text now appears in the new typeface.

Installing Font Support on Windows XP

If you are using Windows XP, additional components may be required in order to display Arabic text on your computer. This installation requires administrator privileges and a Windows XP CD. If you do not have administrative access to your computer, ask your system administrator for assistance.

  1. Go to Control Panel > Regional and Language Options > Languages. If you do not see Regional and Language Options, go to Control Panel > Date, Time, Language, and Regional Options > Regional and Language Options > Languages.
  2. Check Install files for complex scripts and right-to-left languages.
  3. Drag and drop the file into the newly opened window.
  4. Click OK.
  5. Follow the instructions on the screen. You may need to restart your computer for the changes to take effect.

If Arabic text still does not display correctly, you may be encountering system configuration issues linked to your computer. Consult the Windows Help documentation (Start > Help) or the Microsoft Web site for more information. For further assistance, contact your system administrator, Microsoft technical support, or your hardware vendor.

Installing Font Support on Windows 2000

If Arabic text does not display correctly on Windows 2000, you may need to install the NFLC's KacstBook font.

The Arabic rendering subsystem of Windows 2000 (Service Pack 3 and below) suffers from a software defect that may prevent the KacstBook font from displaying correctly. You may need to install an additional system component, USP10.CAB, in order to view Arabic text on your computer. You must have administrator privileges to install the USP10.CAB file.

 USP10.CAB Installation Instructions
  1. Obtain USP10.CAB. Contact your system administrator for assistance.
  2. Open the file using WinZip. If you do not have WinZip, you can download the free version.
  3. Extract the file USP10.DLL and copy it to the following location:
    C:\Program Files\Internet Explorer
  4. Close all Internet Explorer windows.
  5. Open a new Internet Explorer window and navigate to this page again.
  6. Click View Sample Text to verify that Arabic text is displaying correctly.

USP10.CAB is a part of Internet Explorer 6's installation package for Windows 98. If for security reasons you wish to obtain the file directly from Microsoft, you can do so by installing Internet Explorer 6 on a Windows 98 machine and looking for the USP10.CAB file at the following location: C:\Windows\Windows Update Files\

If Arabic text still does not display correctly, you may be encountering system configuration issues linked to your computer. Consult the Windows Help documentation (Start > Help) or the Microsoft Web site for more information. For further assistance, contact your system administrator, Microsoft technical support, or your hardware vendor.

Enhancing Readability on Mac

Mac OS X ships with Arabic language support already installed, so Arabic text should display correctly. Users of OS X 10.5 or 10.6 can download and install the NFLC's KacstBook font for enhanced readability. Follow your system's instructions for installing font files.

Audio Support

The audio player built into the lessons will use the browser plug-in for Windows Media Player, RealOne Player, or Quicktime. If none of these players is available, the audio can still be played with any external media player capable of playing mp3 files.
