Hey Brian,
You're talking about installing the particular framework upon the initial installation of your app? Right now wyBuild doesn't do initial installs (this is coming with wyBuild 2.7.0). There are quite a few ways to handle this now (pre-wyBuild 2.7). In your installer (see the step-by-step walkthrough for different installer options) you can detect if the appropriate framework is installed, and if not installer it using the bootstrapper:
If you need example code we'll be glad to provide it. We'll be making this all much easier with wyBuild 2.7.
