RESOLVED :Using VSI(1.1) to install several projects

Newbie to VSI (1.1) transfering from PDW

I have a set of 6 VB programs to distribute in a single package. I have read that that for best practice I should create separate installer projects for each. How do I then combine them so that users get 6 installation processes in a row without having to start each one separately?

Grateful for any help
Barry
