The installation of Bio7 is similar to the installation of the Eclipse environment. Simply decompress the downloaded *.zip file in a preferred location on your file system. After decompressing with a standard zip-tool (like WinZip, Win Rar) the typical file structure of an Eclipse based application will be created. To start the application simply double click on the Bio7.exe file.
