Thanks for the reply Manuel. I understand how this would work, but I was hoping not to have to download the full program as I'm running an older machine (see below), and an updater program is usually smaller, and I've already downloaded the 7.5 updater. I'm just not sure if I should run this updater directly on the v7.3 that I already have installed on my computer, or if the 7.5 updater needs to have v7.31 installed first.
Do you know if the updaters are sequentially dependent on one another? Or if the latest Updater includes any/all of the info of any previous Updater?
BTW - I'm running on an older machine: 450 MHz PowerPC G4 / OS 10.4.11 / 1.38 GB SDRAM - so the smaller the files, the better.
