I'm needing to upgrade our 4.0(2) machine to 4.0(4) before moving to a new machine and up to 5.x.
Anyway, I'm looking in the Unity Archives in the Download section and see three different CD images:
CD1 - Image Application
CD2 - Voice Board
CD3 - Image ENU
Do I need all of these to complete an upgrage to 4.0(4)?
