Bob — sorry for the slow reply.
1) Good question… I’ll have to dig around for the release notes for specifics, but it uses a new licensing system (so activation won’t get lost so easily) hence the need for new serial number. There were several bug fixes too, which is the main reason we always suggest using the latest version.
2) The safest, cleanest procedure would be to:
a) back up your emitter library files somewhere
b) uninstall pI3
c) install the new version
That being said, you can probably skip step B.
3) When installing the new version you’ll get the option to run in trial mode or enter a serial number. You can run in trial mode as it’s fully functional, then contact support@genarts.com for a new serial number. Once you get it you can use the “enter serial number” shortcut in the pI3 application folder (Mac) or Start menu (Windows). Or you could contact support before installing the update and skip the trial mode step.
Alan.
