updatingScript.1.6Base.ps1

## v1.6 - 2025-06-02
# Added a condition to handle an empty critical processes array.
# Added pre-flight check for running applications
# This script only works for .msi files.
# It will download the file, install it, and then clean up the installer file.
# It will check for running applications.
# This script is a base script that can be used to update any software.
# It is not specific to any one application.
# It is a template that can be used to create a script for any application.
