Before you can use any application, you sometimes ought to create an installation using a software installer.
When you get some application, it is usually shipped in an achieved distributive form.
Programmers who wish to save time or customer support service costs you can choose to use an open source or commercial application installer.
Microsoft has made the Windows Installer for its Windows system that helps developers making install with ease.
There are a number of other commercial installation software applications available for Windows XP: InstallShield, Smart Install Maker and some others.

Talking of installers, it would be wrong not to say a few words about their cousins,that is uninstallers.
Some years ago a number of solutions could not be uninstalled properly without the assistance of dedicated 3rd-party applications.
Nevertheless, these days most software solutions feature more or less adequate uninstallers, so you do not have to think a lot about obtaining some other application to delete things off your hard drive.
But 3rd-party uninstallers have not disappeared just yet.
Another reason is that some solutions choose not to delete themselves entirely leaving some features behind.
Trojan and spyware applications pose one more hazard to your system.
If the program you have just installed appears to have some bad intentions, a third party uninstaller might prove to be the very useful.
Uninstallers sometimes include some extra functionality such as handing cache memory and managing temporary files, and so on.
