I checked my version and I'm way back at build number 370. This is a surprise because I have the debug version of InDesign set up to auto-update in the Adobe Application Manager.
This means that I need to manually get the latest. Since this account is my personal account that I use for posting to the forums, I logged in with the company account and entered the Adobe Partner Connection Portal in my quest to find the latest debug version.
Not having much success. All I have is a simple page with a title "Events" and a subtitle "Live and Online Customer Events". There are some other links but none seem to be developer related.
I can't remember how I got to the debug build before. Any hints how to navigate to where the latest debug build of InDesign CS6 is located?
