Created Unassigned: WCFDataServices Prerequisite Issue [21531]

I was able to consistently see this in a build I was doing and don't know if anyone else has seen it.

I'm doing an offline build on a W2K8 SP2 box, installing SP2013 SP1 (media from MSDN) with SS2K12 already installed. Things seem to run smoothly through a number of prereqs until we hit the WCFDataServices area. The system seems to want to look for the version 5.6 (after instaling 5.0), and when it can't find it it tries to look on the 'net, but this being an offline build (and the server I'm running this on doesn't have access to the 'net) it errors out. See below:

Adding the line to run/execute the 5.6 install in the AutoSPInstallerFunctions.ps1 (InstallPrerequisites function) gets me past this, but it's probably a quick fix.

Has anyone seen this behavior?

Thanks! - M
