PowerPoint for the web doesn't play Shockwave Flash (.swf) files. To work around this limitation, convert the file to an .mp4 file encoded with H.264 video (a.k.a. MPEG-4 AVC) and AAC audio. The RealPlayer Converter (for Windows computers) or the Any Video Converter (for Mac or Windows) are free converters that can be found by searching the web.
