This policy setting controls the ability to turn off shared components. If you enable this policy setting, no packages on the system get the shared component functionality enabled by the msidbComponentAttributesShared attribute in the Component Table. If you disable or do not configure this policy setting, by default, the shared component functionality is allowed. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Windows Installer!Turn off shared components (2) REG: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer!DisableSharedComponent
