I have been asked by the powers that be if Adobe Presenter is written in Visual Basic. I checked settings and credits for the program but no third party info is listed related to Visual Basic. I see that it licenses Windows Media from Microsoft but no other Microsoft credit is given. I checked on Adobe Captivate and it appears to be written using MacApp. (Same as Photoshop). However, I see no such listing in Presenter for what it is created in.
