Download & Install 2.2 Beta2

Windows

Context Free 2.2ß2 (v16) (3.1MB) for Windows 98 and later. The download file is an executable installer, just run it. You need to have version 2.0 or later of the .NET runtime. If you do not have .NET or you have version 1.0 or 1.1 then the installer will abort and ask you to get .NET using Windows Update. The installer will also install the runtime libraries from Visual Studio 2005 SP1.

If you do not have write access to your system directory or if you want to install a stand-alone copy of Context Free to removable media (a CD or a USB drive for example) then use this Zip file: Context Free 2.2beta2 stand-alone (v16) (2MB). Both methods of installing work, but it is better to put the libraries in the system directory if you can.

Macintosh OS X

Context Free 2.2ß2 (v19) (536kB) for Mac OS X 10.3.9 and later. Just copy the application from the disk image to your Applications folder.

Posix / Unix / BSD / Linux / DOS

Download the source code and build using make. You'll need a C++ compiler, flex (not lex), bison (not yacc) and the libpng graphics library. Most of this should be installed or easily available on any modern operating system distribution. See the README.txt file in the source for build and run instructions. The Windows CLI client might build under Visual Studio 2005 Express, I haven't checked. Source Code
