The VTK Cube Puzzle application does not require any specific computer platform or operating system to be present. It rather requires the following third party software to be installed, in the order listed:

• Tcl/Tk (version 8.4 or higher)
  Tcl/Tk homepage: www.tcl.tk/software/tcltk
  
  
• Python 2.x (version 2.4 or higher)
  Python homepage: www.python.org
  
  Important note: The VTK Cube Puzzle application will not work with 3.x versions of Python, because it is not backward-compatible to the 2.x versions.
  
  
• VTK (version 5.0 or higher)
  VTK homepage: www.vtk.org
  
  It is likely that you will need to compile VTK from source. Important note: VTK needs to be installed with Python wrappers enabled: when configuring the VTK software set the configuration variables VTK_WRAP_PYTHON and BUILD_SHARED_LIBS to ON. If you do not find these variables, then consult the appropriate documentation on how to enable the Python wrappers.
