Creative Cloud installs... how to kill all conflicting processes

Perhaps you can script it so the script only runs if no one is logged in.

#!/bin/sh

# Abort operation if someone is logged in.

    if [ `who | grep -c console` != "0" ]
    then
        echo "Someone is logged in at the console."
        echo "Aborting script."
        exit 0
    fi

Thanks for the idea, but we only deploy CC apps via Self Service, so unfortunately that is not an option for us.

You most definitely do not want to kill those Adobe processes. That would imply an Adobe application is running and someone is working in it. The approach I took at my previous job was to make self service items that ran a script. The script would check for all Adobe processes and warn the user to close it before they could proceed. It does a few other things too like check that the computer has sufficient space and is plugged into power. Once the script goes through all its checks, if the Adobe processes are not running it will then call a custom trigger (a second policy that actually has the Adobe installer). That second policy that it calls should have a custom trigger name obviously, have the installer, and also do an inventory update.

The parameters you would need to fill out are as follows:
Parameter 4: Needed Free Space (e.g. 10) (calculated in GB)
Parameter 5: Application Name (eg. Great Big Title)
Parameter 6: Estimated Time to completion in minutes
Parameter 7 - 11: custom trigger names

#!/bin/bash

available_free_space=$(df -g / | tail -1 | awk '{print $4}')
osvers=$(sw_vers -productVersion | awk -F. '{print $2}')
needed_free_space="$4"
app_name="$5"
Time="$6"
PowerSource=$(pmset -g ps | grep "Battery Power")

CustomTriggerPolicyName1="$7"
CustomTriggerPolicyName2="$8"
CustomTriggerPolicyName3="$9"
CustomTriggerPolicyName4="${10}"
CustomTriggerPolicyName5="${11}"

Wow. Thanks @bpavlov This looks great. Will definitely get testing on it. Thanks for sharing!
