In the Properties dialog, enter the path of the Flash .swf file or uniform resource locator (URL) to the Movie field. If the presentation file and the flash file are in the same folder, you could only enter the flash file name, then close the Properties dialog.

Issues about sharing the Powerpoint .ppt on another computer

To share the Powerpoint on another computer, you need to copy both the .ppt file and .swf file, and place the two files in SAME folder, and only enter the File Name (without path) in the above Properties dialog.

There is an option EmbedMovie in the above Properties dialog. Theoretically, if you set its value to True, the Flash SWF movie will be embedded into the Powerpoint .ppt file, and you do not need to copy the .swf file along with the .ppt. But when we test this option, this function just does not work on Windows 7 and Vista. It maybe a bug of Microsoft Powerpoint, or maybe the Security Settings on Windows 7 and Vista.
