Heads up if soemone was having this problem as well.
I encountered this problem recently. The problem is that, when you have routing add-in turned on, configuration publisher is not displaying. It shows the standard selecting window.
I am running SW 2013 SP5. After discussion with my VAR, they were able to reproduce the error as well. They went on to discuss directly wit SW Tech personnel. They were able to reproduce the same on SP5 and 2014 SP1. The SPR 748785 was created (Configuration publisher does not work properly when turn on routing add-in).
Hopefully it will be resolved soon
