I was unable to understand your question correctly. "Can anyone tell me where that application is located after install? " Did you mean you want to know the location(where the file is located in your hard drive) of Presenter Video Creator ? You can also refer to this link(ensure you change the "show me" section from "new" to "all").
Yes. That's correct. Adobe Presenter is a plugin which appears inside PowerPoint 2007, 2010 as a seperate tab.
For the first time, it also comes with a video recording tool which is powerful yet very simple to use.
Hope you are working well with Adobe Presenter now and let us know if you are finding any issues and need any help.
