Unattended installation is an installation technology in which the setup automatically installs with minimum/no interaction with user. This technology is mainly used for installing Operating Systems(OS) in servers and PCs and large-scale roll-outs. The logic of unattended application is that the answers(keystrokes,mouse-clicks and other user inputs) are stored in a file. Then, during the setup process, instead of prompting you for installation and configuration information interactively, Setup follows the instructions contained in the answer file. As unattended installation uses an answer file to install and configure the application, there is minimal interaction from users during the setup process. This reduces the number of errors that are introduced during the setup process and the same configuration can be applied to multiple systems. Unattended installation is much faster than interactive setup because, Setup does not have to prompt user for configuration information and wait for them to enter it; instead, Setup reads configuration settings from that answer file.
Most of the application’s setup that we use in our daily life can be made into unattended. I think, Auto-it is the best one to make automation scripts. AutoIt v3 is a freeware BASIC-like scripting language designed for automating the Windows GUI and general scripting. It uses a combination of simulated keystrokes, mouse movement and window/control manipulation in order to automate tasks in a way not possible or reliable with other languages (e.g. VBScript and SendKeys).
Unattended installation packages are very helpful for corporate users. Common application like Office suite, Media player, Compression utlity are hosted in a file server and deploy to client with single click. it can also integrate with installation CD of Operating system. Nlite is an application to customise windows OS installation. we will try to cover the Nlite usage also
We will get back to you with some useful unattended scripts for popular applications.
