I need a program installer for Windows that is free or open source, customizable and creates small installer files.
I would be using this to create a mmorpg game client installer for my private server. I will need to make use of this installer repeatedly as soon as my server goes live, to keep my player's software up to date with updates. I have attempted to use NSIS, but I have found it to be rather complicated.
One of my primary concerns is file size.
