title: Register ActiveX exe server using WiX
body: <p>I have several VB6 ActiveX server exe files which need to be registered on install before they can be used.</p>
  
  <p>I have tried using Heat to extract the information but it only generates a file element.</p>
  
  <p>These files can be registered by calling them with the /regserver switch and unregister by calling them with the /unregserver switch. I understand this is not the correct way to this. Instead I should add the registry keys and other required elements to my wix source.</p>
  
  <p>My question is how do I find out what registry keys and other element I require to register these ActiveX exe files. Seeing as Heat seems unable to harvest this information.</p>
