CAUSE
This issue may occur if the Office Source Engine service (Ose.exe) startup
type is set to Disabled. By default, the Office Source Engine service startup
type is set to Manual. Microsoft Windows Installer uses a custom action to
start the Office Source Engine service. However, Windows Installer cannot
start the Office Source Engine service if the Office Source Engine service is
disabled.
