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

So, I need to search the target client computers registry for the information to see if its alredy installed. If it finds it, dont run setup.exe. If it doesnt find it in the registry, run setup.exe. How do I do that using custom actions?

Thanks!
 
Ive looked at that page before, and it doesnt 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!
