ArcGIS Explorer Layer - Unknown or Missing Coordinate System

Question asked by on Sep 19, 2014

I am having trouble with my layers. When ArcGIS Explorer Users open my map files some of my layers are coming up with the message Unknown or Missing Coordinate system. It is odd to me because different files do it on different computers.... I know that the layer files referenced have projection information associated with them...


The layers are created in ArcMap 10.2.2 and we are running the latest version of Explorer with the expansion packs installed.


Any suggestions on how to resolve this would be great.


Thank you,
