Change Existing Installation

Hi,

How do I script an NSIS installer so it can also be used to change the existing installation?

e.g. user can go back and chose "option 2" instead

Thank you for replying.

What I mean is, after the user has installed the files they can run the setup again to change the files.

I guess what I need to know is
1. How to detect an existing install and list which components were installed
2. How to allow the user to uninstall individual components and install different ones instead

You can remember sections with memento.nsh but the actual install/uninstall logic is something you have to code yourself.
