I recently came across the following error message when adding Server 2012R2 features. It indicates that the source files should be specified even through they already were.

Add-WindowsFeature : The request to add or remove features on the specified server failed. Installation of one or more roles, role services, or features failed. The source files could not be downloaded. Use the "source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see http://go.microsoft.com/fwlink/?LinkId=243077.

Thanks to Terence Luk I found my answer. After removing security update KB2966828 the problem goes away.
I suspect that this problem is resolved in later updates as I have not come across it before, and the server in question was a few months out of date.
