  Hi. You could use something like this:

  $elevated = $False
  $WindowsIdentity = [System.Security.Principal.WindowsIdentity]::GetCurrent()
  $WindowsPrincipal = new-object System.Security.Principal.WindowsPrincipal($WindowsIdentity)
  $admin = [System.Security.Principal.WindowsBuiltInRole]::Administrator
  $elevated = $WindowsPrincipal.IsInRole($admin)
  Write-Host "Check if running elevated... " 
  
  if ($elevated -ne $True)
  {
  	$errorcode = 1
  	Write-Host "Not running as Administrator"
  	Read-Host "Press enter to exit"
  	exit 1
  }

  It is not try/Catch but it will do the trick

  Use a Requires statement at the first line of the script. Check the help

  #Requires -RunAsAdministrator
  
  Get-Help about_requires

  I tried this, but it isn't working.  

  1.  #Requires -RunAsAdministrator

  It is the first line in my .ps1 - the script still runs.

  I found my mistake... variable name misspelled $Elevated and $Elevation

  How does $elevated know to switch to True if the $Elevation = True?

  $admin is stating "Administrator"

  $elevation is stating "True"

  However, $elevated = False

  and I'm being returned "Not running as Administrator"

  I'm running the script from an elevated shell.

  THANK YOU!! @Vlad817263
