The process is a bit mysterious based on the tutorials given.
A tutorial on how to create another patch that depends on the previous patch. So, for example, Patch 1 is the update and difference between the full install and the changes in Patch 1. When Patch 2 is created, Patch 2 will be the update and difference between the Patch 1 and the changes in Patch 2.
I've tried creating a patch using the MSI from Patch 1 and the MSI from Patch 2, both having the same the Product Code as the full install. But that failed (thread on that here). So if a tutorial could be created to show exactly how to do this, that would be very helpful.
Based on the tutorials given, if a user were to click on Patch 2, AI would know to download the full install and Patch 1 as well. Right?
