For convenience 64bit Windows and OS X versions of Blender with version 0.4 of the VI-Suite included are available below. Only Windows 7 and OSX 10.10 have been tested although other OS versions may work. The VI-Suite folder within the zip file can be placed anywhere on your system but avoid a destination with spaces in the directory path. Blender can then be launched from within the folder.
Please note that modern versions of OS X do not allow by default the running of applications from unregistered developers. Trying to the run the modified VI-Suite Blender App may result in OS X telling you the application is broken. If this occurs you will have to temporarily turn down the security policy on your version of OS X.
A zip file containing just the VI-Suite for Linux 64bit platforms can be found below. This Linux zip file contains the VI-Suite Python scripts and the Radiance/EnergyPlus Linux executables. The Linux version is installed in a similar manner to a regular Blender addon and the folder within the zip file can either be placed in your Blender installation's addon directory or the zip file selected with the Install-addon-from-file button in Blender's User Preferences Addon section. The Python installation seen by Blender should contain all the required additional libraries such as matplotlib, pyqt5, kivy and psutil.
