Prior to use of any application, you often should make an installation using a software installer.

When you get some program, it is often shipped in an achieved distributive format.

Programmers who want to save time or customer support service costs you can choose to use an open source or commercial application installer.

If you work with Windows operation system, you can use Microsoft Windows Installer that lets programmers install software.

There are some other commercial installation software solutions you can find for Windows XP: InstallShield, Smart Install Maker and some others.

The majority of such applications make distributives that offer a consistent experience for users installing different solutions.

Not happy with commercial install creator programs? There are also a couple of good open source solutions available. Check out Clickteam Install Creater and Innosetup, to name a few.

Many software applications these days are developed for more than 1 system.

Making setups for different platforms often requires quite a bit of effort on the part of developers.

If each installer creator for each system be it Linux, Windows XP, Mac OS or a different platform was created individually, it would require quality assurance,i.e. extra time in production and testing to assure a satisfactory experience to users.

The good news is, though, that you there are alot of cross-system software installer programs.

There is an outstanding commercial software application called IntallAnywhere.

What has been installed once, may have to be removed later.

A couple of years ago many programs could not be uninstalled properly without the help of special third-party solutions.

Third-party uninstallers are seldom used in such a way these days, because they are often less effective than standard uninstall procedures.

Nonetheless third-party uninstallers have not vanished just yet.

Many programs have features that are not deleted by the standard uninstall program.

One more challenge that such programs could assist with is erasing Trojan and spyware.

Such a soultion will not delete itself voluntarily, so a bit of help from a specialized uninstaller might be required.

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