title: What is difference between RegSvr and RegServer?
body: <p>Are <code>/RegServer</code> and <code>/RegSvr</code> the same or different, if different why/how?</p>
  
  <p>For example I have seen (example from a 32-bit OS) this style:</p>
  
  <pre><code>RegSvr32 COM.exe
  </code></pre>
  
  <p>or  </p>
  
  <pre><code>RegSvr32 COM.dll
  </code></pre>
  
  <p>Or as an alternative (which was on a 64-bit OS):</p>
  
  <pre><code>COM.exe /RegServer
  COM.exe /RegSvr
  </code></pre>
  
  <p>Are these different approaches doing the same thing?</p>
