So I have an excel sheet that updates every 30 minutes and been trying to link the sheet to PowerPoint to update during live slide show. I've copy and special pasted as link and set to auto update but only works in edit mode or when the ppt is restarted but never live.

I've searched numerous threads and nothings worked. Downloaded and installed the add in to update links live :http://skp.mvps.org/updtlinks.html which doesn't work.

Thought this would work best: How to update excel embedded charts in powerpoint?

And still no data updates during live slide show. I dont know why either.

Using office2010. Any help would be much appreciated.
