Either publish to a file or extract the contents of the zip to a file and then run the index file (it is an html file, as it launches your browser). You may have the option for showing file extensions of known files disabled, so you don't see the .htm.
The trial version of Presenter is fully functional.
Thanks Jorma for your response. So if the file extensions are disabeled, then the index file should launch the presentation in IE but it doesn't. What else could be the reason why nothing is lauching in IE when I click on the index file?
File extensions are not disable, just not showing for known files. It does what it is supposed to do, launches IE, but when it calls back to the supporting files, they are not available because you are trying to play them from within a ZIP file. Extract the contents out of the zip and then launch the index file.
