Exception opening PPTX files


I’ve encountered PptxUnsupportedFormatException opening the PPTX files listed below, using Aspose.Slides v6.1.0.0. The exception occurs in the PresentationEx constructor.

I am able to open all these files in PowerPoint 2010. I don’t know what version of PPT the original presentations were created in (I am trying to find out).

These two tests seem to isolate the issues I’ve encountered. Each test has one file that creates the exception, and a very similar file that works ok.

* test1: textbox

test1-error.pptx: produces exception
test1-ok.pptx: does not produce exception. textbox was deleted, then replaced with a new one

* test2: master slide shapes

test2-error.pptx: produces exception
test2-ok.pptx: no exception, shapes were removed from master slide layout

Let me know if there is any more information I can provide.
