I need to convert a powerpoint file to the latest powerpoint version in my case pptx 2010. so a ppt file 97-2000 or pptx 2007 should be converted to pptx 2010. the special ability of 2010 is that all media objects (sound/video) can be included in the inner zip file and have not to be in the same folder anymore.
The method Convert2 always throws an error no matter what powerpoint file i take. EnsureAllMediaUpgraded doesn't work neither. SaveAs converts the file format but does not embed media objects.
The only way i know is to remove a video shape and use the add video method, but in this case all effects and animations are lost... so that is a nonsatisfying way.
there must be a way to do programmatically what i can do in the gui of powerpoint 2010. Backstore > Upgrade
Has anyone a solution or idea?
