PowerPoint really does not have any control over Flash movies (really amazing that they can be embedded or played). One of the things PowerPoint cannot interpret is the Stop/Loop/or other commands that affect playback. Further, if you leave the slide with the Flash movie and come back during the same presentation it has been looping the whole time, so you won't be at the beginning of the movie.

The best solution is to install the free "FlashBack" add-in (http://skp.mvps.org/flashback.htm). But it has to be installed on any computer the flash file is to used (so distribution of presentation with Flash can be tricky).

 Hi All,

 I have a flash movie (swf), bought it online to put in a presentation.
 This swf is looped by itself.

 But i don't want to play it as a loop in my presentation.
 Is has to run only from start to end and then it has to stop.

 When i set 'loop' on 'false' it don't stops looping.
 What can i do?

 Thanks, best regards,

 Max.
