step1
Make Flash animation with Adobe Flash CS5 or Flash Banner Wizard. Copy the Flash .swf file to the SAME folder as your Powerpoint .ppt file.

step2

Open the Powerpoint .ppt or .pptx file with Microsoft Powerpoint 2010, and select the slide in which you want to insert the Flash movie. Click menu File -> Options. This will show up the PowerPoint Options window.

step3

On the left panel of PowerPoint Options dialog, click Customize Ribbon. Select Developer check box on the right panel. Then click OK.

step4

On the presentation window, click Developer Tab. Click the More Controls icon in the Controls group. In More Controls dialog, select Shockwave Flash Object in the list, click OK.

step5

After that, the mouse cursor shape will become a small cross. Click on the slide and drag the mouse, this will draw a rectangle on the slide. You can resize the rectangle by dragging the sizing handles. Right click on the rectangle, select Properties in the popup menu, this will show up the Properties dialog.

step6
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.

Click F5 to preview the Powerpoint Slideshow.

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.
