This extension provides the same functionality that currently exists in Visual Studio 2010 for Visual Studio Installer projects. To use this extension you can either open the Extensions and Updates dialog, select the online node, and search for "Visual Studio Installer Projects Extension," or you can download directly from this page.
Once you have finished installing the extension and restarted Visual Studio, you will be able to open existing Visual Studio Installer projects, or create new ones.
For those of you looking for an improved deployment experience in Visual Studio, we are continuing our partnership with Flexera to provide InstallShield Limited Edition as our in-box solution (ISLE, http://blogs.msdn.com/b/visualstudio/archive/2013/8/15/what-s-new-in-visual-studio-2013-and-installshield-limited-edition.aspx). ISLE is a great solution for those customers looking for added capabilities not found in Visual Studio Installer Projects, such as TFS and MSBuild integration, support for creating new web sites and ISO 19770-2 Tagging support, etc.
You can download a version of this extension compatible with Visual Studio 2017 here.
