In short, programs for computers (or software) are a set of components, without which a computer cannot fully perform all its functions. At the head of the software that is installed on a personal computer (PC), of course, is the operating system. The first place for almost twenty years has been taken by Microsoft with its Windows (98, XP, 7, Vista). Today, a product from Bill Gates is installed on almost 90% of computers around the world. Therefore, if you ask yourself a question about how to install the program, then you need to understand that almost all of them are developed specifically for "Windows".
In other words, the OS is just a collection of basic programs that are combined by one graphical shell. By default, Windows includes such popular programs as Internet Explorer, Windows Media Player video and audio, text editors , etc. However, their capabilities are clearly not enough for modern users, so installing programs on a computer is a must after installing "Windows".
The vast majority of programs are distributed in a “packaged” (archived) form. Therefore, for the normal installation process, they must be "unpacked" (for this, "WinRAR" or any other archiver is suitable). In the Windows OS, the installation process in most cases occurs automatically and requires minimal user activity. We select a folder or create a new one in one of the sections of the hard drive, and then “unpack” the installation exe-file of the program into it. Next, double-click the left mouse button and run this file and now select the folder in which all the program components will be located. Make sure that there is enough space on the disk (usually programs check this parameter and give a corresponding notification), otherwise the program will not be installed completely.
Often, those who do not know how to install the program run the wrong files. Typically, the installer file is called setup , or install . By default, all programs are installed in one folder - Program Files, which is located on the local drive in the root folder of "Windows". However, if you are installing a computer game, it is better to change the settings by specifying a path to another disk so as not to clutter the disk with the OS with large files.
It also happens that the user knows how to install the program, and does everything right, but nothing works. The fact is that for certain software to work properly, certain components are required. For example, a 2012 computer game is unlikely to “go” without the latest version of "DirectX", and an audio player - without installed codecs for sound ("K-Lite Codec Pack", etc.). After installing some powerful applications or games, you may also need to restart your computer.
Removing programs (uninstalling) should occur from a special manager, which can be called up from the control panel (“Start” - “Control Panel” - “Add or Remove Programs”). Select the unnecessary program and click "Delete." Here you can install the missing components of "Windows" (for example, "Word") from the disk. Some programs are also distributed in special image files that have the format .iso or .img . In order to open a similar format, any program for creating virtual images ("Alcohol", "DAEMON Tools") is suitable.
This basic information is enough to understand how to install the program.
