Windows Installer is Windows' resident software that is responsible for installing processes as well as updating and removing applications. Developers can use it to author a setup file that consists of a single installation package.
Additionally, your files, folders, registry keys, and new accounts are also safer with this program installed on your PC, thanks to its MsiLockPermissionsEx feature. Windows Installer also has the ability to enumerate all components installed on the computer and obtain the key path to each component.
Windows Installer 5.0 is compatible with Windows 7, 8, 8.1, Windows Server 2008 R2, 2012 and 2012 R2. For Windows XP, Vista, Windows Server 2003 and 2008, you must download Windows Installer 4.5.
