System.NullReferenceException when opening a PPT

I am trying to run the pictures demo and get this error:
An unhandled exception of type ‘System.NullReferenceException’ occurred in aspose.powerpoint.dll

when calling:

Presentation pres = new Presentation(fis);

the filestream is created correctly.


Could you attach your ppt file please or send it to me by email?

Here’s the PPT. Thanks

Do you use old version of Aspose.PowerPoint?

1.9.0 - 2.0.2 throw exception:
“Dual format MS PowerPoint 97-2002 and 95 is not supported.”

It appears that I do have an old version. I downloaded a new version, but must have installed the wrong one. Thanks. Sorry to trouble you.
