Skip the SwifPlayer part for now please. The situation has changed a little. I ended up adding the video within Powerpoint (Office 2015) itself.
I just used the "insert video" using ppt's own "insert video" icon (it's the 1st slide), and then hit F5 (run the slide show), it shows the 1st slide (but not the video), and advances to the next slide etc. So, then I noticed that, if you RIGHT click on the video placeholder, it shows "start" and then you choose "automatically", THEN it shows fine....EXCEPT (and here's my updated question) now, when I run the presentation (I try to see myself as the end-user), it gives "SECURITY ALERT: Your current security settings do not allow this action". Of course I can go in and adjust my security settings, but that doesn't help the end-user since I want to make it so that it autoplays the video, but without security warnings. Hopefully you can help me here: my updated question:
What I'm hoping to learn now please is what's the best way to add an .swf video to Powerpoint (Office 2015) in Windows 7 32 bit SO THAT it's compatible with most users (so they don't get ActiveX, security warnings, etc). Looking for simple solution if possible. Thanks in advance very much for your solutions.
You're running into a security feature in current versions of Office. Flash content is click-to-play in office documents. Unfortunately, one of the major vectors for malware infection inside enterprise networks was end-users clicking on legitimate-looking office documents with embedded plug-in content. To mitigate this infection risk, embedded content like SWFs are click-to-play. If it were possible to circumvent the security dialogs, they would not provide a meaningful defense against this attack vector.
There's a guide on the Microsoft support side on embedding videos directly into your presentation:
If you're looking to display a simple Flash animation, you're probably better off converting it to video. You can do this directly from Flash Professional, as long as you have the original source files (.fla). If you don't have the .fla, you might do the hacky thing and use a screen-capture utility like Adobe Captivate / Camtasia Studio / etc - to make a video recording of the animation playing on the local computer.
If you're looking to embed a complex Flash-based interactive element into the document, then you should probably think about putting those elements on a website and linking to them from the powerpoint presentation. In my personal opinion, it would be better to move away from this use-case than to train your students to ignore the security dialogs which really do provide meaningful barriers to would-be attackers.
VERY helpful and thoughtful response. Thanks. I've been thinking each day to get back to your earlier, but was too busy, but wanted to make sure I showed my appreciation. I like the idea of converting the swf to .mp4 since I don't have the .fla (it's created in a different tool, called mix fx). I wanted to find out if others here (I know you're with adobe of course) can recommend some good, free converters. I tried Doremi, but it looked blurry. I want the output to have an excellent quality. Thanks for some ideas. I do know I can search for "free swf to mp4", but I value the experience of intelligent, well-minded people. Thanks for your help so far Jerome! That did answer my question very well. Oh, in case it matters, it's not for embed. Thanks very much.
