We would like to extend our thanks to those centres and individuals who have bought the GCSE Mathematics DHT®. The response has been fantastic. We have developed a patch to tweak DHT® package based on your experiences and software-related issues. As promised, the first of our updates is now ready for download.

Installation instructions:

• Click on the link
• Download Zip* file
• Unzip/save to preferred location
• Double-click icon to run
• Follow the installer prompts

*If you require WinZip, a full evaluation version of WinZip 9.0 SR-1 is available for download.

Although the patch is designed to seek the already-installed software, those centres that had difficulty with CC3 networks or alternative server locations should follow the same procedures as before.

A demonstration of how to set the .NET security settings is available from:
