|To put both exe in a single exe, you need a wrapper. There are alot of wrappers on the internet but I haven't tried any.|
But, do you really want to bind exe files??
You said about configuring user screens after install, why not put the link of that exe after install in your installation file, so that after install the file links you to that exe that does this user profile configuration.
Hope this helps. Do get back with results :)
