install_applications_wmi.ps1

<# 
I wrote this script to install a VCM client on a number of servers.  We do not have winrm enabled on any of our servers so I
used the Invoke-WmiMethod cmdlet to install the application.  

This script will copy the nessicary files to the destination server then install, it will also provide logs for installation and
connection errors.
