eDrawings 2014 API - How to supress Document Manager prompt?

I just upgraded from the 2012 to 2014 ActiveX eDrawings viewer in my C# project, and now I have an annoying pop-up about the document manager, that every user sees every time they preview a drawing.  They don't want or need the DM or Solidworks on their system.  How can I suppress this dialog?  I feel like I dealt with this before, in the 2012 upgrade, but can't remember how I dealt with it.

PS: After much research I did find out how to supress the search for a SNL checkout:

 

edrwModel.set_EnableFeature(EModelView.EMVEnableFeatures.eMVDisableSNLCheckout, true);

but no luck for the DM dialog.

Thanks,

Randy
