I was working on a task in Word's VB Editor — that's Word 2016 for Mac — that needed associative arrays, and quickly found references to "Scripting.Dictionary", and then figured out that it comes from a library that is not installed with Office 2016 for Mac.
I found this question pointing to a third party library after a lengthy search. 2+ hours more searching, and I still can't figure out how to load it into Word. I found this reference to sandboxing, but it's talking about .dylib files and I've got a .cls — seems like a mismatch. There are oodles of references to loading libraries in Excel, but nothing I've found regarding Word has worked.
So, if I have a .cls file containing the source code for a library such as the one I've linked, how do I bring it into Word?
