Answer: The regular re-installation process will work for an earlier build. HOWEVER, the post-upgrade process will NOT copy the data from your current Foxhound database to the one that's being installed when the current installed build number is later than the one that's being installed. That means you lose your sample data and option settings, and it means you will have to activate Foxhound as if it were a brand new installation.
