The Kalypso package is distributed in the form of a zip archive which can be downloaded here. The package is installed by unzipping the archive into any directory. Kalypso does not make any changes to system files or directories. To uninstall the package, just delete the installation directory tree.
Kalypso should run under any recent 32-bit version of Windows, although it has only been tested under Windows 2000 and Windows XP. The appearance of fonts and Windows may change on your computer due to version differences, or your choice of custom options. Some of the visualization graphics do not work well unless the screen height:width display settings are in the ratio 1.6 (e.g. 1440x900, or 1680x1050).
If you notice odd or irritating behaviour, or discover a bug, please report it to the author.
There is no obligation to register Kalypso. Updates are infrequent, but users are encouraged to suggest improvements.
