PowerShell module to interact with the Self-Elevation functionality of Ivanti AppSense Application Manager

Start-ProcessAMSelfElevate.psm1

<#
    .Synopsis
    This module can be used to invoke the Self-Elevation functionality of
    Ivanti AppSense Application Manager

    .Description
    This module uses the AMShellIntegration.AMShellContextMenu COM component to
    invoke the Self-Elevation functionality of Ivanti AppSense Application 
    Manager.

    When enabled, Self-Elevation can be used to run (selected) applications
    with Administrator privileges. Generally, this functionality is only
    exposed from Windows Explorer. Using this module, it is possible to call
    this component directly (with arbitrary arguments).

    .Example
    Import-Module .\Start-ProcessAMSelfElevate.psm1
    Start-ProcessAMSelfElevate -FilePath cmd.exe -ArgumentList /k,calc.exe -WorkingDirectory $env:USERPROFILE
#>
Function Start-ProcessAMSelfElevate {
Param([Parameter(Position = 0, Mandatory = $true)] [string]$FilePath,
    [Parameter(Position = 1, Mandatory = $false)] [string[]]$ArgumentList,
    [Parameter(Position = 2, Mandatory = $false)] [string]$WorkingDirectory)
    If ([Environment]::Is64BitProcess -ne [Environment]::Is64BitOperatingSystem) {
        Throw "Please load this module in a 64-bit PowerShell"
    }
