Actually print rite updates their software regularly, but for some reason all versions must have the version name 1.5.5. If you install latest from website you should see it appear in title as 1.6.2. With release 2.0 coming soon you will get a new slicer Slic3r Prusa Edition and a bit later also a new CuraEngine.
Copying the printer settings to original will of course also work. The slic3r and curaengine profiles are just files on disk. Slic3r will appear anyway and CuraEngine is u subdirectory in workdirectory that you can be copied to new work directory. Just note that each printer has it's set of slicer data here so copy the right subfolder named like your printer.
