How to Make a Windows Installer

| Comments

Introduction

There are many tools which can be used to make an installer, like NSIS, Install Shield, Advanced Installer, WiX, InnoSetup and even Visual Studio. Here I just show you how to make an installer by NSIS. NSIS (Nullsoft Scriptable Install System) is a professional open source system to create Windows installers. NSIS is script-based, which means you configure your installer by a script. That makes it small and flexible.

You can download NSIS at the official website: http://nsis.sourcefore.net, but I recommend you download the Unicode version of NSIS here: http://www.scratchpaper.com, because if your installer is not in English, it will not correctly displayed in some circumstances, for example, your installer is in Chinese, but you want to install it in a English-version Windows, you may see garbled fonts.

UAC Problem

On Vista and Windows 7 systems, you should met the UAC problem when you make your installer with NSIS. There IS a NSIS UAC plug-in, and you may download here: http://nsis.sourceforge.net/UAC_plug-in. But in my opinion, this plug-in is not elegant, as it creates a new progress when it elevate privileges, which makes the decompress process appears 2 times, one for each progress.

The installer of GTalk doesn’t use UAC and it doesn’t need administrative privilege at all! While the installer of QQ (another instant messenger), needs administrative privilege and it can’t install without the privilege. Both of the above installers doesn’t use UAC plugin, assuming they are made with NSIS.

Is there a way between GTalk and QQ? I don’t know. I’m finding a way that if both low and high privilege users can install my software without the ugly UAC plugin.

Use 7z to Reduce the Size of the Installer

My test shows the size of my installer reduces about 20 percent when I use 7z to compress my installer. To do this, you need to use this plugin to extract 7z package: http://nsis.sourceforge.net/Nsis7z_plug-in. You have to write another script to compress your program package with 7z. In addition, you need to adjust the information for the size of volume needed to install during the installing process.

An NSIS Bug

You would loose the focus of your program if you keep dragging the installer window while the progress bar is running until the next window appears.

NSIS Is Not Cool Enough?

Maybe not.

Example

To learn how to use NSIS, you can reference the official document http://nsis.sourceforge.net/Docs/, while there is an easier way, to read an example. This is the NSIS script for Pidgin (from http://nsis.sourceforge.net/Pidgin). Though it’s not excellent code, you will learn a lot if you are a newbie to make installers.
