SOFTWARE INSTALLATION

Installation is a computer program; it is the act of putting the software program into a computer. These programs can be executed by copying it to a suitable computer location. Installation process includes unpacking of files completed in a compressed form.

The installation program is a computer program that installs files such as drivers, applications or other software onto a computer. Some installation programs are used to install the files what they contain. Other computer programs are the general purpose and made work by reading the installed software packages. The installer may check for available mass storage and system suitability storage space. The installation process is varies for each computer and each program.

Some software is simply installed by copying that files into desired location and there is no proper installation process. This is same for many users, its running under Mac OS, Amiga OS, MS-DOS, and Atari TOS. These are the early versions of operating system and it is very common. The “de facto” standard in Mac OS X applications is used for several windows applications.

There are some versions which do not require installation, and this can be run from a DVD, CD or USB drive without disturbing the other operating systems installed on the computer.

Software installation includes the modification of:

• Non-shared and shared program files
• Directories/folders
• Configuration of original settings for computer programs
• Variables

Some installation process:

- Silent installation: During this process, it does not display windows or messages.
- Unattended installation: performing the installation without the user interaction.
- Answer file: The answer file is used in Microsoft windows installation process on many machines.
- Headless installation: Installation is performed without connecting the video outputs to computer but the attended information is performed by connecting the serial cable or LAN to computer.
- Clean installation: Clean installation is performed in the lack of interfering factors. The clean software installation is made by formatting its objective separation before the normal installation process.
- Flat installation: Installation is made by a CDs or DVDs to a hard drive.
- Network installation: An installation is performed from a shared network drive. This is the simply a copy of Flat installation.

Sometime this installation is goes wrong, because sometimes setup utilities or software cause some problems that is depends on system control. Before the new software installation, clear the pathway of obstacles and also follow the roadmap when in installation process.

If you are downloading the programs through the internet, scan the programs before you install. If the antivirus software does not scan the downloaded files from viruses, then open the antivirus program and scan the program file. In addition, activate the virus protection before installing the program. If you are disable the other programs, but make your virus protection in running mode.
