Inno Setup 4.0.9 has been released.?I use and recommend it for packaging & deployment of Windows desktop and client applications.?Its scripting based compiler system provides a lot of flexibility. And, it is?open source (Borland Delphi).
A few colleagues at work are also writing a similar installer program in VB.NET. They tell me that its also going to have a scripting based compiler system (like Inno Setup). I’ll post?a demo of their product as soon as I get to review it myself.
