How to create an msi project for more than 1 project


it is very easy to make a msi project for any single project .. but my question is that, i want to make a msi project that contains 2 Existing Project and 1 SQL SERVER Setup within it.

i want to install SQL SERVER from msi then install 2 exe .. Please give me any suggestion or reference .

Thank You

DONT DO IT. Point. Installing SQL Server rom within an MSI is not supported for the obvious problem of updating it.
