Overview
The Microsoft® Windows® Installer is an application installation and configuration service. WindowsInstaller-KB893803-v2-x86.exe is the redistributable package for installing or upgrading Windows Installer. This revised package replaces the previously released redistributable package named "WindowsInstaller-KB893803-x86.exe" and addresses the issue discussed in KB Article 898628: Windows Installer fails silently after you upgrade to Windows Installer 3.1.
Note for users of previous versions of the Windows Installer: The new Windows Installer redistributable follows a new naming convention that contains a knowledge base reference so it is easier to identify which version of the Windows Installer will be installed. The previous naming convention, INSTMSI.EXE, will no longer be used.
Supported Operating Systems: Windows 2000 Service Pack 3; Windows 2000 Service Pack 4; Windows Server 2003; Windows XP; Windows XP Service Pack 1; Windows XP Service Pack 2
Windows Installer 3.1 Redistributable supports Windows 2000 with Service Pack 3 or later, Windows XP, Windows XP Service Pack 1, Windows XP Service Pack 2 and Windows Server 2003. Windows Server 2003 Service Pack 1 contains Windows Installer 3.1 and therefore can't be installed or upgraded by this redistributable.
