# Automated AppX Package Installer - by Elektro #
# --------------------------------------------- #
 
# This script will find any AppX package files within the current directory (without recursion),
# print info about the package, print a message in case of the package is already installed,
# and install the package in case of it is not installed, handling errors during installation.
 
# ---------------------------------------------------------------------
 
# Takes a string argument that points to an AppX package name or file,
# then it uses a regular expression to match the package string pattern
# and returns a custom object with the Name, Version, Architecture,
# PublisherId and other properties.
#
# Parameters:
#   -PackageString: A string that points to the file name
#                   or full path of an AppX package file.
#
# Returns:
#   A PSCustomObject object with these properties defined:
#     [String] Name
#     [String] Version
#     [String] Architecture
#     [String] PublisherId
#     [String] FullName
