Now I encounter this question. I use installshiled Primer to make a installation program. All it need to do are copying some dll files to windows system directory which are self-registered, installing MySQL and MyODBC and executing a script for MySQL.
I choose installscript project and use LaunchAppAndWait to call the setup program of MySQL. I put the script in OnFirstUIAfter(). But after it finished copying dll files to system directory, the installation terminated when MySQL installation program was loaded.
I want to know that in my case what the most common way is to implement. If you can tell me which key words I need to use in google or simply give me a URL, that would be fine.

Thank you in advance.
