Using Custom Action in Visual Studio 2005 Deployment Project (under Vista)

There are some quirk using Custom Action in Visual Studio 2005 and if your development machine is Vista you have even more trouble to sort. Here are what I faced recently :

• Unhelpful error message. See : "Windows Installer fails on Vista with 2869 error code.". In my case, I just run the resulting installer in an XP machine to get more informative message.
  
• When you add Custom Action for Commit phase you need to include your Custom Action Library to Install phase although you don't do anything on it e.g: override it. If you don't do this it you will have error can not save state or something. More about it here.

Thanks to google, the solutions are only one (or several) search away.
