title: How to get path for an executable given ONLY the executable name?
body: <p>I need to <strong>get the path to an executable</strong>, and the information that I got is only the executable name. I <strong>need the</strong> <strong>file path</strong>, <strong>not the .exe name</strong></p>
  
  <p>Example : 
  I have "arma3.exe" only, now I need to find the path to it. I need something like this 
  "C:\Program Files\Arma3\arma3.exe" &lt;-- the file path</p>
  
  <p>I am <strong>NOT</strong> asking for "How do I find the path to my CURRENT WPF APPLICATION executable path" nor "how do I get the file name given X path".</p>
  
  <p>And please, don't ask me why I need to find the path or bla3. I have my own reason to do this.</p>
