One of the more interesting things in MDT is the “Application bundle” application install option. What an application bundle allows is the ability to install multiple applications, in order, as dependencies. Think of it more as a logical container for applications that need to be installed, perhaps in a specific order, or as prerequisites for another application (like, for instance, installing Visual Studio 2008 prerequisites, Visual Studio itself, and then the latest service pack).
Adding the application(s)
To create an application bundle that will show up in the list of applications to install (or be available to configure via a task sequence), you first need to add all of the applications to MDT that will make up the bundle. This is done similar to adding Office 2007 as I documented in my post on creating an MDT deployment point – you must create a New Application and add it’s source files to the deployment share. I’ll document quickly how to add the Windows Live Essentials components to your deployment share and “bundle” them (instructions on getting the .msi packages you’ll need from the Windows Live Essentials downloadable package can be found here, if you do actually want to try this).
