We run multiple versions of Solidworks with Windchill WGM. Recently, we've added SW2016. Currently, we maintain SW2014, 2015, and 2016. Just recently, post installing SW2016, I started receiving the following pop up message when starting SW2015: "Document Manager available is not valid for use, switching to non DM Mode." (see attached screenshot) It started occurring directly after installing SW2016.
The pop up message reoccurs sporadically, and is more of an annoyance than a hindrance. I've search and not found anything related to this, and am not sure how to begin diagnosing the issue. Thoughts? It seems to be impacting the WGM more than anything. There are random lock ups and a bit of lag when performing routine operations like synchronization of the workspace or updating components.
We are now seeing this message in 2016 & 2017. The pop up message now occurs as a wgm type message (as it appears when you check in or check out a part/assy/etc).
