I have a system in operation on 6.1.31 with 2 terminals and the server is XP. Trying to migrate to a new server with Win 7 64 bit (can be 32 bit if that's easier). Have a running spare server with XP and 6.1.31 for testing and when I try to install from 6.7.60 CD I get a message "Another version of this product is already installed. Installation of this version cannot continue. If you are attempting to upgrade, please use Aloha Update." What is Aloha Update and where can I find it?
