QTIViewer has being renamed CCReader and released as opensource under the Apache 2 licence. The source code and a binary with installer are available from sourceforge.
CCReader is a IMS Common Cartridge Content Package and IMS QTI 1.2 question viewer which allows teachers to view the content of learning packages witout installing them on a VLE. CCReader is a Windows (98 or later) application, and also can run on Linux or OS-X computers using Wine or Crossover Office to provide Windows emulation. (The splash screen doesn't display, however this is a very minor issue.)
The QTI item engine, Oghma-C, is written in standard C++ and so can be ported to other platforms. It has been tested (with some wrapper code) as a PHP module for Windows and Linux and s a .NET DLL for ASP.NET as well as as a static library for Visual C++.
