This news (good and bad at the same time) was published in July but which very few people caught (I caught it myself only during the weekend from http://coolthingoftheday.blogspot.com/2010/09/visual-studio-setup-deployment-projects.html).
The bad news: the “Visual Studio Setup and deployment Projects” feature of Visual Studio 2010 (and previous versions) will be retired in the future version of Visual Studio.
Now the news is that InstallShield Limited Edition is free for VS2010 customers. To learn more about how to obtain InstallShield LE, read http://blogs.msdn.com/b/deployment_technologies/archive/2010/04/20/installshield-limited-edition-is-available-for-download-in-visual-studio-2010.aspx.
