title: registering com dll in wix
body: <p>If not self registering. then how do we perform the COM dll registering while installation using WIX?</p>
  
  <p>As per the <a href="http://wix.tramontana.co.hu/tutorial/com-expression-syntax-miscellanea/com-applications" rel="nofollow">tutorial</a>, I used ComPlusApplication example (non .net dll). But its not working. It fails to register.</p>
  
  <p>I can register using regsvr32 from the command line successfully.
  I read about not creating custom actions for registering com dlls.</p>
  
  <p>SO what is the best approach?
  If we need to use heat, where do we write the commands and add the result wxs to the main project? </p>
