VS2010 Publishing an app with ClickOnce

This is my first experience with ClickOnce, so I hope that it's possible to do what I want.

My app relies on another program to do some encryption, so I want to have that program be a prerequisite. Do I need to create a bootstrapper for it? Basically I want to run a batch file that will silently install the program and add a public key, and then go ahead and install my program.

Can anyone point me in the right direction?

Nevermind, I was able to get it figured out. I used the Bootstrapper Manifest Generator to create my manifest, and through some trial and error figured out where to copy the needed files to in the publish location.

I'm really surprised that MS hasn't built this into the Publish section in VS, as it has to be a pretty common scenario.
