Nobody likes to install and configure software, everyone likes to use it, work with it, install all kinds of add-ons, plug-ins, skins. That is, customize software, make it suit their tastes and preferences. This process is routine, uninteresting, takes time and effort and so there are very few people who like to do it again and again. But sometimes you have to do it, for example, after your operating system crashes or you have a hard disk failure. Everything starts from the beginning: operating system installation, driver installation, service pack installation, software installation, then comes tuning the operating system, software configuration and localization, entering registration data (in commercial software)... It is okay if you have all software at hand on disks and you have to install it only on one computer. But then you will have to do the entire configuration manually anyway. And what if you have no distribution packages or your registration keys are lost? You will have to contact the developer's support service. That is when you are in for some nervous work involving searching for the necessary software and restoring the working environment you had before. The following question emerges: how to automate it? In practice, there are only three ways to solve the problem of .

Let us take each method and tools implementing it in detail.

A lot of installers allow you to automatically install software using special keys (command line parameters). The user does not need to do anything in this case. All values will be set to their defaults. Every installer has its own set of such keys.

Examples.

InstallShield: /s setup.exe /s

Windows Installer: /qn REBOOT=ReallySuppress setup.msi "/qn REBOOT=ReallySuppress"

Inno Setup: /VERYSILENT setup.exe /VERYSILENT

Pluses:

+ high installation speed without user attendance

Minuses:

Special programming languages (scripting languages) are used to write scripts. The most popular is AutoIt. Its main purpose is automating work with the Windows graphical interface.

AutoIt can:

AutoIt includes a script interpreter and compiler. If you write and debug your own script, you can easily convert it into a regular exe file that already runs as a standalone file.

Pluses:

Minuses:

- having to learn the scripting language and the Windows operating system.

There are special program for creating an automatic Windows and software installation disk. The most well-known ones are nLite and MultiSet

nLite. The program can create a bootable disk with the following operating systems: Windows 2000/XP/2003. It also allows you to integrate some service packs and, if necessary, remove some components from the operating system (Media Player, Internet Explorer, Outlook Express, MSN Explorer, Messenger, etc.). As a result, you get the ISO image of a bootable disk with Windows.

Pluses:

Minuses:

- impossible to automatically install any custom software

MultiSet ? the program for for the automatic installation of Windows and sets of software. As a result, you get bootable disks of three

types:

Advantage MultiSet:

MultiSet already studied at University!

The Academy of Modern Information Technologies has created a special course dealing with unattended Windows and software installation. The aim of the course is to provide students with theoretical and practical skills allowing them to create a bootable Windows distribution package that will be automatically installed on a PC with maximum number of drivers and software without the user's attendance. The MultiSet software is studied within this course. This program is a leader in the field of automating unattended software installation. Upon completing the course, students will get enough knowledge to create a completely automatic Windows distribution package that will be installed on a personal computer without a single mouse click and then automatically install all drivers (these drivers work for 95% of personal computers) and automatically install all software necessary for this or that computer. MultiSet became the de facto standard in this field long ago that is why educational institutions choose this product.

Pluses:

+ creating a bootable disk with Windows and a set of software

Minuses:

- impossible to enhance a created script

Summary.

All methods, and the above programs in particular, serve the same purpose ? create a bootable disk for the automatic Windows and software installation. But they do it differently. nLite and SetupStudio are tailored towards the modification of the Windows distribution package, i.e. the integration of service packs and patches into it. As to the automatic installation of other software, it is done easily ? the user has to either use silent keys or specify the approximate installation algorithm based on the one the program offers. MultiSet placed the emphasis on the automatic installation of any software together with Windows making it possible to use silent keys and automatic configuration.

The programs can complement each other: a script written in AutoIt can be easily executed in MultiSet, an nLite disk can automatically install sets of software from MultiSet.
