Run the script / application after installation (using VS Setup Project)

I need to execute a console application script after installing my application. Depending on the version of Windows, it adds some data to the registry.

How to do this using a Visual Studio installation project?

Note: I speak after , because I read in How to perform a custom action before installing files when using the VS installation project? that it is impossible to do this before, but in my case it does not really matter.
