  645.     This function will install the LabTech agent on the machine with the specified server/password/location.
  646.  
  647. .PARAMETER Server
  648.     This is the URL to your LabTech server.
  649.     example: https://lt.domain.com
  650.     This is used to download the installation files.
  651.     (Get-LTServiceInfo|Select-Object -Expand 'Server Address' -ErrorAction SilentlyContinue)
  652.  
  653. .PARAMETER Password
  654.     This is the server password that agents use to authenticate with the LabTech server.
  655.     (Get-LTServiceInfo).ServerPassword
  656.  
  657. .PARAMETER LocationID
  658.     This is the LocationID of the location that the agent will be put into.
  659.     (Get-LTServiceInfo).LocationID
  660.  
  661. .PARAMETER Rename
  662.     This will call Rename-LTAddRemove after the install.
  663.  
  664. .PARAMETER Hide
  665.     This will call Hide-LTAddRemove after the install.
  666.  
  667. .PATAMETER Force
  668.     This will disable some of the error checking on the install process.
  669.  
  670. .EXAMPLE
  671.     Install-LTService -Server https://lt.domain.com -Password sQWZzEDYKFFnTT0yP56vgA== -LocationID 42
  672.     This will install the LabTech agent using the provided Server URL, Password, and LocationID.

  916. .SYNOPSIS
  917.     This function will reinstall the LabTech agent from the machine.
  918.  
  919. .DESCRIPTION
  920.     This script will attempt to pull all current settings from machine and issue an 'Uninstall-LTService', 'Install-LTService' with gathered information.
  921.     If the function is unable to find the settings it will ask for needed parameters.
  922.  
  923. .PARAMETER Server
  924.     This is the URL to your LabTech server.
  925.     Example: https://lt.domain.com
  926.     This is used to download the installation and removal utilities.
  927.     If no server is provided the uninstaller will use Get-LTServiceInfo to get the server address.
  928.     If it is unable to find LT currently installed it will try Get-LTServiceInfoBackup
  929.  
  930. .PARAMETER Password
  931.     This is the Server Password to your LabTech server.
  932.     example: sRWyzEF0KaFzHTnyP56vgA==
  933.     You can find this from a configured agent with, '(Get-LTServiceInfo).ServerPassword'
  934.    
  935. .PARAMETER LocationID
  936.     The LocationID of the location that you want the agent in
  937.     example: 555
  938.  
  939. .PARAMETER Backup
  940.     This will run a New-LTServiceBackup command before uninstalling.
  941.  
  942. .PARAMETER Hide
  943.     Will remove from add-remove programs
  944.  
  945. .PARAMETER Rename
  946.     This will call Rename-LTAddRemove to rename the install in Add/Remove Programs
  947.  
  948. .EXAMPLE
  949.     ReInstall-LTService
  950.     This will ReInstall the LabTech agent using the server address in the registry.
  951.  
  952. .EXAMPLE
  953.     ReInstall-LTService -Server https://lt.domain.com -Password sQWZzEDYKFFnTT0yP56vgA== -LocationID 42
  954.     This will ReInstall the LabTech agent using the provided server URL to download the installation files.
