The software greenius is distributed free of charge. The installer is a zip-archive containing the actual installer called Greenius_Setup_x.x.x.x.exe, where the x's are replaced by the version code. The compressed format is used since most systems prevent downloading an exe-file. Extract the zip-archive, run the exe-installer and follow the instructions.
Important hint for users with an existing installation of Greenius:
The installer tries to detect whether there is already a previous version of greenius on your computer. If so, the installer will use the same directory for the update. This means that all existing files wil be overwritten by the installer. This applies of course only for those files which are delivered with greenius. In case you have modified data files with their own names, they will left unchanged by the installer. If you want to keep your complete old installation, you should choose a new path name when running the installer.
