Installation computer programs Wikipedia. Installation or setup of a computer program including device drivers and plugins, is the act of making the program ready for execution. Because the process varies for each program and each computer, programs including operating systems often come with an installer, a specialized program responsible for doing whatever is needed for their installation.

Installation typically involves code being copiedgenerated from the installation files to new files on the local computer for easier access by the operating system. Because code is generally copiedgenerated in multiple locations, uninstallation usually involves more than just erasing the program folder. For example, registry files and other system code may need to be modified or deleted for a complete uninstallation. OvervieweditSome computer programs can be executed by simply copying them into a folder stored on a computer and executing them. Other programs are supplied in a form unsuitable for immediate execution and therefore need an installation procedure. Once installed, the program can be executed again and again, without the need to reinstall before each execution. Common operations performed during software installations include These operations may require some charges or be free of charge. In case of payment, installation costs means the costs connected and relevant to or incurred as a result of installing the drivers or the equipment in the customers premises. Some installers may attempt to trick users into installing junkware such as various forms of adware, toolbars, trialware or software of partnering companies. To prevent this, extra caution on what exactly is being asked to be installed is needed. The installation of additional software then can simply be skipped or unchecked this may require the user to use the custom, detailed or expert version of the installation procedure. Such malicious conduct is not necessarily a decision by the software developers or their company but can also be an issue of external installers such as the Download. CNET. 2NecessityeditAs mentioned earlier, some computer programs need no installation. This was once usual for many programs which run on DOS, Mac OS, Atari TOS and Amiga. OS. As computing environments grew more complex and fixed hard drives replaced floppy disks, the need for tangible installation presented itself. A class of modern applications that do not need installation are known as portable applications, as they may be roamed around onto different computers and run. Similarly, there are live operating systems, which do not need installation and can be run directly from a bootable. CD, DVD, USB flash drive or loaded over the network as with thin clients. Examples are Amiga. OS 4. 0, various Linux distributions, Morph. OS or Mac OS versions 1. See live CD and live USB. Finally, web applications, which run inside a web browser, do not need installation. Attended installationeditOn Windows systems, this is the most common form of installation. An installation process usually needs a user who attends it to make choices, such as accepting or declining an end user license agreement EULA, specifying preferences such as the installation location, supplying passwords or assisting in product activation. In graphical environments, installers that offer a wizard based interface are common. Download software in the CDDVD Images Utils category. Attended installers may ask users to help mitigate the errors. For instance, if the disk in which the computer program is being installed was full, the installer may ask the user to specify another target path or clear enough space in the disk. Silent installationeditInstallation that does not display messages or windows during its progress. Silent installation is not the same as unattended installation see below All silent installations are unattended but not all unattended installations are silent. The reason behind a silent installation may be convenience or subterfuge. Malware is almost always installed silently. Unattended installationeditInstallation that is performed without user interaction during its progress or with no user present at all. One of the reasons to use this approach is to automate the installation of a large number of systems. An unattended installation either does not require the user to supply anything or has received all necessary input prior to the start of installation. Such input may be in the form of command lineswitches or an answer file, a file that contains all the necessary parameters. Windows XP and most Linux distributions are examples of operating systems that can be installed with an answer file. In unattended installation, it is assumed that there is no user to help mitigate errors. For instance, if the installation medium was faulty, the installer should fail the installation, as there is no user to fix the fault or replace the medium. Unattended installers may record errors in a computer log for later review. Headless installationeditInstallation performed without using a computer monitor connected. In attended forms of headless installation, another machine connects to the target machine for instance, via a local area network and takes over the display output.

Scheduled or automated installationeditAn installation process that runs on a preset time or when a predefined condition transpires, as opposed to an installation process that starts explicitly on a users command. For instance, a system administrator willing to install a later version of a computer program that is being used can schedule that installation to occur when that program is not running.

Clean installationeditA clean installation is one that is done in the absence of any interfering elements such as old versions of the computer program being installed or leftovers from a previous installation.

Since the interfering elements are absent, a clean installation may succeed where an unclean installation may fail or may take significantly longer. Network installationeditNetwork installation, shortened netinstall, is an installation of a program from a shared network resource that may be done by installing a minimal system before proceeding to download further packages over the network. This may simply be a copy of the original media but software publishers which offer site licenses for institutional customers may provide a version intended for installation over a network. InstallereditAn installation program or installer is a computer program that installs files, such as applications, drivers, or other software, onto a computer. Some installers are specifically made to install the files they contain other installers are general purpose and work by reading the contents of the software package to be installed.
