Answer 1

I would like to add something to the Eric Bonnot's answer : The answer worked out partially as I worked on a IIS server with a non-admin user with the powerpoint PIA.

I noticed that I could not open a pptx file if this one had a media (picture for example) in it.

The "hack" was to add also the rights to the windows user (the one using the PIA) on the systemprofile/AppData directories.

Hope this helps
