Application Repackaging


Application Packaging

It is the process of converting third party installation packages into windows installer packages with the customizations your organizations need. Using windows installer service as a packaging and deployment mechanism can help lower the costs associated with application deployment and maintenance.
Installation Programs were created by many different vendors, where the installation behavior was controller by a proprietary script.
Problems with traditional setups called Legacy Setups here on) related to corporate environment include Requiring administrative Privileges to perform an installation, requiring an administrator to visit each target system, log in , install the software, make changes to the configuration and log out.
There was no common mechanism for customizing a setup or performing a silent install (Installation runs in the background with out asking many questions like where to install the application, enter the cd key…..).
Because each setup program provided its own rules, interactions among two or more applications sometimes caused conflicting results. For example, newer versions of shared files might be replaced with older ones. As a result, applications that required the newer version of the file were not successfully and completely installed. A failed installation could cause other applications not to function.
Windows Installer provides consistent and reliable installation for all applications, which prevents newer files from being overwritten by older files.Inter-application conflicts can occur when uninstalling one application removes files shared by other applications on the computerWindows Installer addresses this problem by keeping track of the resources that Windows Installer-based applications use. For example, several products include the Grid Control for Microsoft® Visual Basic, which uses Windows Installer. After this control is installed, Windows Installer detects its presence. When you install other products that use the Grid Control, each product is added to the client list for the Grid Control. Windows Installer references these client lists when installing, upgrading, or removing components.You can avoid this problem by taking advantage of Windows Installer. Windows Installer provides consistent and reliable installation for all applications, which prevents newer files from being overwritten by older files.Windows installer service is a part of windows xp / windows 2000 and windows ME. And can be installed on windows 95, windows 98 and windows nt 4 systems.
