Just install newer version over older one (you do not need to uninstall older version, new version installer will do it for you).
Most settings will keep. There are several exclusions:
1) Keys (shortcuts): we've reworked Undo (instead of 'undelete from rejected') and Copy/Move (several last used destinatiions are stored instead of one). You may need to re-tune these keys.

2) We've deleted several obsolete functions (see list at the end of changes list at http://www.fastrawviewer.com/download#changelog )
And bonus: after you install FRV 1.3 you'll get additional 30 days of trial
