I have a standard PPT that I update every month with new data. I opened the latest version, right click any chart and select "edit data", but nothing happens. I can see in Task Manager that EXCEL.EXE opens up as a result of this, but the Excel table that usually comes up does not appear.
I tested this on a new PPT and created a new chart. It opened the Excel table and let me edit the data. It even let me close the Excel table and then "edit data" again. But once I saved the file, closed Powepoint and then re-opened it, it would not let me edit the data any more.
I tried all sorts of MS hotfixes, but nothing works. I am using Office 2007 SP2 on XP with all the current updates installed. I also ran Office Diagnostics and ran the repair option from the setup menu. Nothing worked.
