I'm a beginner user of Adobe Presenter in Japan.
I don't know why the price of this app differs between for Windows($499.00) and for Mac(Video Express:$1.99).
Although I tried using both version(Win and Mac), I confermed no differences in functions, abilities, and so on.
Please tell me the reason why. i think it's unfair.
Welcome to Adobe Forums.
Adobe Presenter 9 for windows works as a plugin in MS Powerpoint (2007, 2010 & 2013 [32bit])
You can add quizzes, create videos, publish SCORM content and you can convert your Powerpoint Presentation into interactive content.
Adobe Presenter Video Express for MAC is an app which is used for create vidoes and publish them as MP4
The Adobe Presenter Video Express for Mac application should be compared to the Adobe Presenter Video Creator tool (which comes with Presenter 9), but not to the Presenter 9 application. As Vikram stated, Presenter is an add-in for PPT on Windows based computers, and has much more functionality than the Video Express application.
