Interestingly, there are basically two kinds of programs I am sometimes happy to see guided tours embedded in:
* Creation programs (image/video editors, 3D rendering... hell, even a slides program or an IDE). Doesn't mean I won't dismiss them sometimes anyways, but these are tools that often I do want to get an initial idea how to use, that I have allotted some time to play around with, and that are sufficiently complex that a tutorial is justified. These are also places were I can spend 2-5 minutes learning the basics of the tool, because whatever I am about to do with it is going to take the next few hours anyways.
* Videogames (i.e. the tutorial). For very similar reasons to the above ;)
Also, this is always on first install. Getting a tutorial on update for an authoring tool (and to a lesser extent a game) is far less likely to be welcome.
