Visual Studio 2k5 Setup Project

Question

Hi, I've made a LaTeX IDE in C# and I want it to include a distribution, such as MikTeX, to go with it. So what I've done is made a Setup project for my solution but how do I get it to run the setup.exe for the distro before it runs the install? I suspect I can put something in the PreBuildEvents but I have no clue what...? I also thought I could just make a Win App that would run both processes like my own custome Installer but Id ratehr package them all together as one exe. If anyone has any solutions I'd be really greatful Jason
