GPKs created using Desktop 10.2.1 and 10.3.1 work fine with Runtime 10.2.7, but GPKs created using 10.4.1 and 10.5.PR do not. I've been told that certain versions of ArcMap/ArcCatalog are only compatible with certain versions of Runtime, because of an ArcObjects compatibility issue. If so, will 10.4.1 and 10.5 support the Quartz release? [The current Quartz Beta doesn't have a local server yet that I can test.]
