Hi Keith

1. you can just install the 9.1.4 update on top of your current 9.1.3

2. When you install the app builder it installs everything you need for development.
- App builder
- Cloud server (which includes Lianja sql server)
- odbc driver

You do not need to download and install anything other the Lianja app builder for your development machine

There are no reported issues with 9.1.4
