I have this problem when I add new project -> other projects -> visual studio installer -> Setup wizard to create setup project after finish it gives me this problem :

The following files may have dependencies that cannot be determined automatically.
Please confirm that all depedencies have been added to the project.

what is that means ? and how to solve this problem?

I think you need to add a reference to the Flash library. Or copy the DLL to the projects bin\release folder.
