How to create a robust, minimal installer for Wind

Question

I want to create an installer EXE with some specific properties:

1. it should be a single exe file
2. it should be robust (i.e. the technique should be known to work well on any Windows system)
3. it should create only a single file (a .scn screensaver file) in %systemroot%
4. it should add the option to uninstall that particular file in "Control Panel -> Add or Remove Programs" but without creating any new entry C:\Program Files or copying an uninstaller.exe somewhere.

I've seen installers that work like that - so how to do this?

Answer 1

NSIS, MSI any installer can do that for you.

NSIS is pretty small and compact.
