I tried to use a specific format, FileFormat.PPTX_2013, but I get same result; I tried with different version of the library, from the latest 3.7.4 backward to 2.11.2 and still get same exception; 2.10.1 seems to work but doesn't "import" the presentation well. Obviously src points to the file I'm trying to import, and that file is correctly opened with PowerPoint. If I open the file with PowerPoint and save it without make any correction, after that the file is correclty imported.
This behaviour doesn't happen with all presentations, but it occours with a specific file which is the result of a conversion from a pdf; since it contains sensitive information I'd like to share with you in a private way and not directly in the forum, is it possible?
Thank you
Paolo
