title: In a visual studio setup project, how do I prevent a conditional custom action to run?
body: <p>I have a very simple Visual Studio 2010 setup project.
  In this project I have a simple custom action, running a thirdy part executable. Nothing really complicated so far.
  Now, I want to add a parameter, so, when running the installer, I have the option to skip this custom action.
  Let's say, for example, that I want to run my installer using a switch, at command prompt. Something like this</p>
  
  <p>my-msi-name.msi /NOACTION</p>
  
  <p>What I want to achieve is to skip the custom action if this "/NOACTION" is added as a switch, else run it.
  Is this a possible option? I can't find any answer to this question.</p>
