The latest version of Shadowrun Toolbox is 0.4.0, released on 22th may 2015. It's still alpha quality code but can be used for simple characters.
It can be downloaded from Sourceforge.
- srtb-0.4.0-tar.gz contains the sourcecode
- shadowruntoolbox-0.4.0-installer-win.exe is an installer for all Windows systems.
- srtb-installer-0.4.0.jar is an universal installer that can be used on all systems (Windows, Linux, MacOS,...)
Both installers require a Java 8 JRE, the same necessary to run Shadowrun Toolbox.
Complete installation instructions can be found in the Installation Manual.
