Just starting to use Studio Presenter 360. When I open Presenter 360, it prompts me to open PPT. When I do so, I get an error message saying it's an add-in and that I need to install it and try again. I googled this. I then went into PPT and went to Options, and Add-Ins, COM Add-Ins. There is nothing disabled. When I go to COM Add-Ins, Articulate is not an option to add. Please help!
