Installing and Running FDT
From FDT Documentation
FDT is distributed in two ways: as an Eclipse plug-in and as a standalone application. The standalone installation is recommended for users new to the Eclipse platform or for users who want a straightforward install of FDT. FDT as an Eclipse plug-in is useful to users who are familiar with the Eclipse and want to extend a particular Eclipse distribution to include FDT. FDT 4 uses the Galileo ( 3.5 ) distribution of Eclipse and supports Eclipse Helios ( 3.6 ).
When FDT is first installed and run, it will begin a 30 day trial. The 30 day trial is designed to give users a chance to use FDT and become familiar with it’s features. After 30 days, FDT will operate in ‘restricted mode’, limiting it’s capabilities. If FDT is registered with a valid licence key, it will unlock features associated with the provided key.
Before installing FDT, users should make sure they have a compatible version of Java installed. The easiest way to do this Verify Java Version site and follow the on screen instructions for verification. Windows users who haven’t installed Java already will likely have to install Java. OSX users have Java installed by default.
To download FDT’s installer, navigate to FDT’s homepage to register and receive the download instructions via email. Download the distribution of FDT that is compatible for your target operating system. For OSX users, the FDT installation application is distributed as a zip  that will need to be unarchived prior to launching. FDT for Windows is distributed as an .exe  that can be simply run.
Windows users will need to run the installer with admin permissions!
When the installer launches , follow the on screen instructions to choose an installation directory and if desired any aliases ( OSX ) or shortcuts ( Windows ).
