You're encountering a lot more issues than I am. The differences I see:
- Early releases of CCP 1.6 didn't block DPS Desktop installers properly, you might have hit that?
- I'm installing CC 2014 pkgs rather than CC pkgs
- All my CCP pkgs (except DPS Desktop Tools) have a "RestartAction" of "RequireLogout"
- I'm adding updates by exporting new CCP update-only pkgs, rather than using aamporter
- I broke the CCP pkgs into one software title per pkg
Sorry I can't be of more assistance.
