Before you can use any application, you sometimes should create an installation using a software installer.

The majority of solutions you come across these days are published as a distributive.

For developers there are ample opportunities to make their releases more effective using commercial or freely distributed install maker.

If you deal with Windows operation system, you might take advantage of Microsoft Windows Installer that lets programmers making install with ease.

There are a lot of other commercial installation software solutions available for Windows XP: InstallShield, Smart Install Maker and several others.

All of them could create the so-called packages that can let you install software on any Windows system.

Not happy with commercial installer creator applications? There are also a some good open source solutions available. Check out Clickteam Install Creater and Innosetup, to name a couple.

A number of programmers try to make their products work on different platforms.

Making setups for various systems usually requires quite a bit of effort on the part of developers.

If each installation creator for each platform be it Linux, Windows XP, Mac OS or some other system was created separately, it would require additional workload,that is extra time in development and testing to provide a satisfactory experience to users.

Luckily, there are also cross-platform software installer applications.

For example, InstallAnywhere which is a commercial installer creator, or an open source Java install creator for different systems named IzPack.

A software package often has to feature not only an setup creator, but also an uninstaller.

A couple of years ago some applications could not be uninstalled properly without the help of special third-party applications.

3rd-party uninstallers are rarely used this way now, because they are often less effective than built-in uninstallers.

In spite of everything these 3rd party uninstallers are used nowadays.

One of the reasons for that is that some applications choose not to delete themselves completely leaving some features behind.

One more trouble that such applications might help with is erasing Trojan and spyware.

If the soultion that was installed just now seems to show some inadequate intentions, a third party uninstaller might turn to be the thing you need.

Uninstallers often include some extra abilities such as handing cache memory and managing temporary files, and so on.
