Custom actions - how to?

[changobutt]

In my installation package, I want add a custom action to install another app (run its setup.exe) if it's not installed on the target client computer.

So, I need to search the target client computer's registry for the information to see if it's alredy installed. If it finds it, don't run setup.exe. If it doesn't find it in the registry, run setup.exe. How do I do that using custom actions?

Thanks!

I've looked at that page before, and it doesn't help. It just tells you how to add and delete. I need more guidance on how to do my custom action. How to check, and how to use the result of the check to run a certain file (where to check)...

Thanks!
