It just doesn't seem to do anything - I had dragged in the extensions for the deprecated panels and also DataBridge.
When io installed all, it installed the deprecated panels one, but nothing happened with DB - the icon with the cross didn't do anything.
It is a bit odd though, in that the Web Assist menu appears in DW - it did before I tried with DMX Zone. But when I tried testing any of them, I was just getting a very small dialogue box with an exclamation mark icon, and no error message. I assume this is somehow related to it being installed in an earlier version of the Adobe Extension Manager for ab earlier version of Dreamweaver.
My set up here is a new Mac, to which I transferred all the files from the old Mac, but have been reinstalling applications manually as I need them.
As it is now, the WA menu is present, but none of the options do anything it all now.
Is there a way to flush out / remove the the WA extension from DW 2015, and then maybe try again with DMX Zone as a fresh install?
