“with WU1 for 2014 out, and odd, I thought I would let you know I have tested it using the standard WU recipe, and it works fine. It requires access to the initial deployment to run silently, which is different from previous Revit web updates. And so far as I can tell there is no command line switch to tell it where to find the deployment.
We shall see if this is the new (and bad!) way of doing things, or just a one time anomaly.”
