Before you can use any program, you often have to create an installation using a software installer.

When you get some solution, it is often delivered in an achieved distributive format.

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

For those who work with Windows platform, there is a popular solution called Microsoft Windows Installer that helps developers create installation.

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

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

Not happy with commercial setup creator programs? Those who prefer open source applications might check out Innosetup and a couple more programs that might be obtained for free.

Many software applications these days are made for more than one platform.

It is often quite a hard job to create various installation packages for some different systems.

Developers have to produce and assure the quality of each installer, be it for Linux, Mac OS or Windows XP.

Fortunately, there are also cross-system install maker applications.

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

Talking of installers, it would be wrong not to mention their cousins, i.e. uninstallers.

A couple of years ago some programs could not be uninstalled correctly without the assistance of special third-party applications.

Nevertheless, nowadays the majority of software programs feature more or less adequate uninstallers, therefore you do not have to think a lot about getting a different program to erase stuff off your PC.

In spite of everything such third party uninstallers are used nowadays.

Many programs have functionalities that are not deleted by the built-in uninstall solution.

An additional difficulty that such applications can assist with is deleting Trojan and spyware.

If the soultion that was installed just now seems to demonstrate some unusual intentions, a 3rd party uninstaller might turn to be the very useful.

If you would like a better way to manage cache memory or temporary files uninstallers may also be of use.
