Do you not install Web Deploy from the Web Platform Installer?
Last updated by Brady Stroud [SSW] 8 months ago.See historyYou should not Install Web Deploy from the Web Platform Installer, but instead download the installation from the IIS website (http://www.iis.net/downloads/microsoft/web-deploy).
The reason for this is that the Web Platform Installer does not install all of the components required for continuous deployment, but the downloaded package does.
