There is no Macromedia Captivate. Captivate was a Macromedia
product . . .
Adobe bought Macromedia (the whole company) after Captivate
version 1 was released, then created version 2 branded for Adobe.
So the long and short of it is that if you have version 1, you have
Macromedia Captivate, and if you have version 2, you have Adobe
Captivate.
Hope this helps ...
