Notes

Setup developers can use Windows Installer 5.0 to author a single installation package capable of either per-machine installation or per-user installation of the application. For more information, see Single Package Authoring. The internal consistency evaluator ICE105 checks that the package has been authored to be installed in a per-user context. An application capable of being installed, updated, run, and removed by a standard user without elevation is called a Per-User Application (PUA.) A PUA can provide a better user experience, minimize effects on the system and other users of the computer, and reserves UAC prompting to situations that actually require the elevation of the user's privileges. The Single Package Authoring features of Windows Installer 5.0 can facilitate the development of Per-User Applications.

Services configuration options enable a Windows Installer package to customize the services on a computer. For more information, see Using Services Configuration.

Beginning with Windows Installer 5.0, a Windows Installer package is capable to secure new accounts, Windows Services, files, folders, and registry keys. The MsiLockPermissionsEx table can specify a security descriptor that denies permissions, specifies inheritance of permissions from a parent resource, or specifies the permissions of a new account. For information, see Securing Resources.

Windows Installer 5.0 can enumerate all components installed on the computer and obtain the key path for the component. For more information, see Enumerating Components.

Windows Installer 5.0 running on Windows Server 2012 or Windows 8 supports the installation of approved apps on Windows RT. A Windows Installer package, patch, or transform that has not been signed by Microsoft cannot be installed on Windows RT. The Template Summary property indicates the platform that is compatible with the installation database and should include the value for Windows RT.
