Cause

There is a certain Windows update which must be installed on the Microsoft Windows 2012 R2 operating system that is required for Veeam Agent for Windows functionality - KB2919355.

The update contains necessary Universal C Runtime components that are required for Veeam Agent for Windows 5.0.0.4301.
