The launch icon disappeared on my dock. How do I find it?

Do you mean the iTunes icon (this is the iTunes Store forum), or for a different app ? If the app is still in your Applications folder on your Mac then you should be able to click-and-drag it from there back onto your Mac's dock.

Do you have the Applications folder on your dock, of if not then you should have a Applications folder off the root of hard drive.

Or you can open Finder, do control-F to open the search, set Kind as Application

then type in the name of the app that you want to add to the dock into the search field top right of the Finder screen, and then click-and-drag the app from the search results to the dock.
