Unsolved Where to get Qt SDK installer source code

[Yagiza]

Trying building Windows installer for my Qt application with Qt IFW. There are some nasty issues with my installer on some platforms which relate to lack of administrator previlegies. Different experiments with elevation of previlegies gave me no results. A dialog asking for logging in with administrator previlegies appears, but after successful logon nothing happens - installing of components fails.
So, I'd like to look into source code of Qt SDK installer to see, how it should be made, to work correcty. Is it available?
