Text converter - pb tyo read a ppt from netherland with a Powerpoint 2007 in France

[Jean-Pierre Bidon]

Hi to all
I received a ppt file - so a 2003 version - from a correspondant in the
Netherland. I am in France (may be - ? - the fact that the countries are
different has smthg to do with the problem).
I can't open it meither with a 2003 powerpoint nor with a 2007 powerpoint,
and same negative result with a powerpoint viewer.
The document itself was originally created by a 2003 powerpoint, then
modified by a 2007 powerpoint, but saved in ppt (ie 2003 version).
When I double click on the document, it cannot be opened (id when I select
"open" inside of the software), and an error lmessage appears that say:
"Powerpoint ne peut pas lire à partir de <arborescence et nom du fichier>.
Aucun convertisseur de texte n'est installé pour ce type de fichier"
That means: " Powerpoint cannot read this file. No text converter is
installed for this type of file"
My question are:
- what is this text converter that is mentionned?
- I tried to download such a text converter, but didn't find any?
Thanks a lot for any help.
