Follow whatever instructions they provide for the installation.  It's probably 
just a modified version of Gromacs with an additional tool, so the installation 
would be like any you would do for a normal Gromacs distribution.  Make sure to 
set a proper installation path to avoid overwriting your existing Gromacs

They don't.  People have discussed this problem previously.  In theory, you 
could probably re-create whatever necessary input files (.top, .tpr, etc) under 
version 3.3.1 and process any trajectories created with more modern versions. 
Version 3.3.1 is ancient and there have been hundreds of bug fixes and feature 
enhancements since it came out.
