Yea I know :-)

It's the way I do it now: having a "Loader" which does licensing, updating, etc... and the main stuff is in a DLL file. Everything is installed / uninstalled using NSIS.

My Post is more an enquiry if my ideas can be realized, having only 1 file for easyness doing everything and telling windows how to use the exe file. If it's not possible it's still okay, I'm just askin.
