I often use PowerPoint for presentations. Confronted with such disadvantage: PowerPoint is not installed on each computer. Advise me an alternative solution, as you can get without having to install PowerPoint, and is it possible?
Microsoft provides PowerPoint Viewer free of charge. It won't allow you to modify PowerPoint presentations, but it will allow you to play them. I don't think there's a portable version that can be run from a thumb drive, but it's a small install for computers that don't have the full Office treatment.
You can use Windows Live Webapps.
You can also use the Broadcast feature which allows all your users to watch the same slideshow.
You send a link to your users and they can all watch your slideshow. You can control which slide they see from inside Powerpoint.
As far as I know, PowerPoint is able to produce a standalone .exe file that plays your slideshow. I guess that would be a suitable solution for almost any computer, because you do not need to install anything and you do not need any user privileges at all. Unfortunately I do not have MS Office on my own, but I guess you should find the option to do that on "export" or "save as". I also heard the it is possible to export the slideshow as flash (.swf) file (I know for sure in LibreOffice) which would be a possibility, too because most systems nowadays have an internet browser with installed flash player.
PowerPoint online or the PPT viewer is the most easiest thing to do. You can also Export all you slides and use the images one-by-one through scrolling. Another possibility is to export it to mp4 format which can be played by almost every device in the world. https://islide-powerpoint.com/en/support/ppt-to-vid I often do this after a presentation to all the attendees and get great feedback on that. Hope this helps for you! Ben
