If Windows 8.1 Update KB2919355 still fails to install on a computer that is running Windows RT 8.1, Windows 8.1, or Windows Server 2012 R2 and you still receive Error 80073712, then download and install Update KB2969339 which has been released by Microsoft to fix this issue.

This issue occurs because a new component in update 2919355 contains a file version that is later than the file version that was already installed on the computer.
