Packaging and Installing

I have been writing software for a while and most of the time the packaging and installation was a challenge to an admissible extent.

Some useful list of packaging software

• Install Shiled aka Install Anywhere (someone bought the other now both are same) - Enterprise level and very flexible , proven
• Null soft
• jLaunch http://download.cnet.com/JLaunch/3000-2344_4-29443.html
• http://installer.excelsior-usa.com/en/ ( something new i came across)
