title: InstallShield LE: Customizing uninstall
body: <p>I wrote a free utility that changes system settings.  Some users mistakenly think that they can undo the changes simply by uninstalling the utility.  When they try to uninstall, I want to show them a message telling them that they have to use the utility in order to undo the changes, and give them a choice of continuing or canceling the uninstall.  How do I do this?
  I am using InstallShield LE with Visual Studio 2010.    </p>
